Maintenance-free battery -charging Note: The following is intended as a guide only. Always refer to the manufacturer's recommendations (often printed on a label attached to the battery) before charging a battery. 13 This battery type takes considerably longer lo fully recharge than the standard type, the time taken being dependent on the extent of discharge, but it can take anything
up
to three days. 14 A constant voltage type charger is required, tooe set, when connected, to 13.9 to 14.9 votts wth a charger current below 25 amps. Using
mis
method, the battery should be usable within three hours, giving a voltage reading of 12.5 vofts. but this Is for a partially discharged battery and, as mentioned, full charging can
take
considerably longer. 15 If Ihe battery is to be charged from a fully discharged state {condition reading loss lhan 12.2 volts), have it recharged by your FIAT dealer or local automotive electrician, as Ihe charge rate is higher and constant super-vision during charging Is necessary.
3 Battery -removal and refitting
Note: Refer to Disconnecting the battery in ifte Reference Section of this manual before proceeding.
Removal 1 Slacken the clamp bolts and disconnect the ctamp from the battery negative (earth) terminal. 2 Remove the insulation cover (where fitted)
and
disconnect the positive terminal lead(s) in
Die same
way. 3 At the base of the battery, unscrew the bolt from the battery holding clamp plate and remove the clamp plate (see Illustration). A Remove the battery from Ihe engine compartment. 5 II necessary the mounting tray may be removed by unscrewing the bolts. On diesel models it will be necessary to remove the relay guard bolts as well.
Refitting 6 Refitting is a reversal of removal but make sure that the positive terminal is connected first followed by the negative terminal.
4 Alternator/charging system - >%•> testing in vehicle
Note: Refer to the warnings given in Safety first! and in Section 1 of this Chapter before starting work. 1 If the ignition warning light fails to Illuminate when the ignition is switched on, first check the alternator wiring connections for security. If satisfactory, check that the warning light bulb has not blown, and that the bulbholder is secure in its location in the instrument panel. If the light still fails to illuminate, check the continuity of the warning light feed wire from the alternator to the bulbholder. If all is satisfactory, the alternator is at fault and should be renewed or taken to an auto-electrician for testing and repair. 2 If the ignition warning light Illuminates when the engine Is running, stop the engine and check that the drivebelt is correctly tensioned (see Chapter 1A or 18) and that the alternator connections are secure. If all is so far satisfactory, have the alternator checked by an auto-electrician. 3 If the alternator output is suspect even though the warning light functions correctly, the regulated voltage may be checked as follows. 4 Connect a voltmeter across the battery terminals and start the engine. 5 Increase the engine speed until the voltmeter reading remains steady; the reading should be approximately 12 to 13 volts, and no more than 14 volts. 6 Switch on as many electrical accessories (eg. the headlights, heated rear window and heater blower) as possible, and check that the alternator maintains the regulated voltage at around 13 to 14 volts. 7 If ihe regulated voltage is not as stated, the fault may be due to worn brushes, weak brush springs, e faulty voltage regulator, a faulty diode, a severed phase winding or worn or damaged slip rings. The alternator should be renewed or taken to an auto-electrician for testing and repair.

7 Starting system • & testing
Note: Refer to Ihe precautions given In Safety firstI and in Section I of this Chapter before stoning work. 1 If the starter motor falls to operate when the Ignition key Is turned to the appropriate position, the following possible causes may be to blame. aj The battery is faulty. b) The electrical connections between the switch, solenoid, battery and starter motor are somewhere failing to pass the necessary current from the battery through the starter to earth. c) 77:© solenoid is faulty. d) The starter motor is mechanically or electrically defective. 2 To check the battery, switch on the headlights. If they dim after a few seconds, this indicates that the battery is discharged -recharge (see Section 2) or renew the battery. If the headlights glow brightly, operate the ignition switch and observe the lights. If they
dim, then this indicates that current it reaching the starter motor, therefore the iao8 must lie In the starter motor. If the lights continue to glow brightly (and no clicking sound can be heard from the starter motor solenoid), this indicates that there is a lairt
In
the circuit or solenoid - see following paragraphs, if the starter motor turns siowfy when operated, but the battery is In good condition, then this indicates that either lae starter motor is faulty, or there is considers resistance somewhere in the circuit. 3 If a fault in the circuit is suspected, disconnect the battery ieads (including ihe earth connection to the body), lt» starter/solenoid wiring and tne engine/transmission earth strap. ThoroygWy clean the connections, and reconnect the leads and wiring, ihen use a voltmeter or J«i lamp to check that full battery voltage is available at the battery positive lead connection to the solenoid, and that the earth is sound. Smear petroleum jelly around ttie battory terminals to prevent corrosion > corroded connections are amongst the most frequent causes of electrical system faults. 4 If the battery and all connections are in good condition, check the circuit disconnecting the wire from the solenod blade terminal. Connect a voltmeter or less lamp between the wire end and a good earth (such as the battery negative terminal), ais check that the wire is live when tne ignition switch is turned to the start position. If It is. then the circuit is sound - if not. the circut wiring can be checked as described Chapter 12. Section 2. 5 The solenoid contacts can be checked
Oy
connecting a voltmeter or test lamp across Ihe solenoid. When the ignition switch is turned to the start position, there should b»a reading or lighted bulb, as applicable. II thars is no reading or lighted bulb, the solenoid is faulty and should be renewed. 6 If the circuit and solenoid are proves sound, the fault must lie in the starter motor. In this event, it may be possible to have tre starter motor overhauled by a specialist, but check on the cost of spares before proceeding, as It may prove more economical to obtain a new or exchange motor

1 Genera! information and precautions

A


Warning: fie/Ore carrying out any work on the electrical system, read through the precautions given in Safety first! at the beginning of this manual, and in Chapter 8. The electrical system is of 12-volt negative earth type. Power for the lights and all electrical accessories is supplied by a lead/acid type battery, which is charged by the alternator. This Chapter covers repair and service procedures for the various electrical components not associated with the engine. Information on the battery, alternator and starter motor can be found in Chapter 5. It should be noted that, prior to working on any component In the electrical system, the
battery negative terminal should first be disconnected, to prevent the possibility of electrical short-circuits and/or fires. Caution: Before proceeding, refer to Disconnecting the battery In the Reference Section of this manual for further information.
2 Electrical fault finding-general information
Note: Refer to the precautions given In Safety first! and in Section 1 of this Chapter before starting work. The following tests relate to testing ot the main electrical circuits, and should not be used to test delicate electronic circuits (such as antHock braking systems), particularly where an electronic con fro/ module is used.
General 1 A typical electrical circuit consists of an electrical component, any switches, relays, motors, fuses, fusible links or circuit breakers related to that component, and the wiring and connectors which link the component to both the battery and the chassis. To help to pinpoint a problem in an electrical circuit, wiring diagrams are Included at the end of this manual. 2 Before attempting to diagnose an electrical fault, first study the appropriate wiring diagram, to obtain a more complete understanding of the components included In the particular circuit concerned. The possible sources of a fault can be narrowed down by noting whether other components related to the circuit are operating properly. If several components or circuits fait at one time, the problem Is likely to be related to a shared fuse or earth connection.

12*2 Body electrical systems
3 Electrical problems usually stem from simple causes, such as loose or corroded connections, a faulty earth connection, a blown fuse, a melted lusible link, or a fautty relay {refer to Section 3 for details of testing relays). Visually inspect the condition of all (uses, wires and connections in a problem circuit before testing the components. Use the wiring diagrams lo determine which terminal connections will need to be checked, in order to pinpoint the trouble-spot. 4 The basic tools required for electrical fault-finding include a circuit tester or voltmeter (a 12-volt bulb with a set of lest leads can also be used for certain tests}; a self-powered test light (sometimes known as a continuity tester); an ohmmeter (to measure resistance): a battery and set of tesi leads: and a lumper wire, preferably with u circuit breaker or fuse incorporated, which can be used to bypass susoect wires or electrical components. Before attempting to locate a problem with tost instruments, use the wiring diagram to determine where to make the connections. 5 To find the source of an intermittent wiring fault (usually due to a poor or dirty connection, or damaged wiring Insulation), a wiggle test can be performed on the wiring. This involves wiggling the wiring by hand, to see if tha fault occurs as the wiring Is moved. It should be possible to narrow down the source of the fault to a particular section of wiring. This method of testing can be used in conjunction with any of the tests descnbed in the following sub-Sections. 6 Apart from problems due to poor connections, two basic types of fault can occur in an electrical circuit - open-circuit, or short-circuit. 7 Open-circuit faults are caused by a break somewhere in the circuit, which prevents current from flowing. An open-circuit fault will prevent a component from working, but will not cause the relevant circuit fuse to blow 8 Short-circuit faults are caused by a shod somewhere in the circuit, which allows Die current flowing In the circuit to escape along an alternative route, usually to earth. Short-circuit faults are normally caused by a breakdown in wiring insulation, which allows a feed wire to touch either another wire, or an earthed component such as the bodysheli. A short-circuit fault will normally cause the relevant circuit fuse to blow.
Finding an open-circuit 9 To check for an opon-circuit, connect one lead of a circuit tester or voltmoter to either the negative battery terminal or a known good earth. 10 Connect the other lead to a connector in the circuit being tested, preferably nearest to the batter/ or luse. 11 Switch on the circuit, bearing In mind that some circuits are live only when tho ignition switch is moved to a particular position. 12 If voltage is present (Indicated either by
3.2 Main fuse box, located on the driver's side of the facie the toster bulb lighting or a voltmeter reading, as applicable), this means that tho section of Ihe circuit between the relevant connector and the battery is problem-free. 13 Continue to check the remainder ot the circuit in the same fashion. 14 When a point is reached at which no voltage Is present, the problem must lie between that point and the previous test point with voltage. Most problems can be traced to a broken, corroded or loose connection.
Finding a short-circuit 15 To check for a short-circuit, first disconnect the load(s) from the circuit (loads are the components which draw current from a circuit, such as bulbs, motors, heating elements, etc). 16 Remove the relevant luse Irom the circuit, and connect a circuit tester or voltmeter to the luse connections. 17 Switch on the circuit, beanng in mind that some circuits are live only when the ignition switch is moved to a particular position. 18 If voltage is present (indicated either by the tester bulb lighting or a voltmeter reading, as applicable), this means that there Is a short-circuit. 19 If no voltage is present, but the fuse still blows with the load(s) connected, this indicates an internal fault in the load(s).
Finding an earth fault 20 The battery negative terminal Is connected to 'earth' - the metal of the engine/transmission and the car body - and
I
IK
J 3.3 To gain access to the fuses, remove the screw and pull the stowage bin away from the facia
most systems are wired so that they only receive a positive feed, the current returning via the metal of Ihe car body. This means that the component mounting and the body form part of that circuit. Loose or corroded mountings can therefore cause a range of electrical faults, ranging from total failure ot a circuit, to a puzzling partial fault. In particular, lights may shine dimly (especially when another circuit sharing the same earth port In operation), motors (eg wiper motors v Ihe radiator cooling fan motor) may run slowly, and Ihe operation of one circuit may have an apparently-unrelated effect on another. Ncie that on many vehicles, earth straps axe uses between certain components, such as the engine/transmission and the body, usually whore there is no metal-to-metal contact between components, due to flexible rubber mountings, etc. 21 To check whether a component $ properly earthed, disconnect Ihe battery, and connect one lead of an ohmmeter to a kwwi good earth point. Connect the other lead to the wire or earth connection being tested. Tha resistance reading should be zero; if not. check the connection as follows. 22 If an earth connection Is thought to be faulty, dismantle the connection, and clean pack to bare metal both the bodysheli and ite wire terminal or the component earth connection mating surface. Be careful to remove all traces of dirt and corrosion, then use a knife to trim away any palm, so thai a clean metal-to-metal joint Is mads. On reassemoly, tighten the joint fasteners securely: if a wire terminal Is being refitted, use serrated washers between tho terminal and the bodysheli. to ensure a clean and secure connection. When the connection is remade, prevent the onset ot corrosion in the future by applying a coat of petroleum idly
or
stlicone-based grease, or by spraying on (a: regular intervals} a proprietary ignition eoater, or a water-aispersant lubneant.
3 Fuses and relays -general information
Fuses 1 Fuses are designod to break a circuit when a predetermined current is reached, in order to protect the components and wiring wttioh could be damaged by excessive current How. Any excessive current flow will be due to a fault in the circuit, usually a short-circuit (see Section 2). 2 The main fuses are located in the fusefcox on the driver's side of the facia (see illustration). 3 To gain access to the fuses, remove tne screw and pull the stowage bin moulding away from the facia (see illustration). 4 Additional fuses and circuit-breakers are located In the engine compartment, and in an

3.4 The auxiliary fusebox, located inside the glovebox behind a drop-down panel auxiliary fusebox, which is located inside the glovebox behind a drop-down panel (see Illustration). 5 A blown fuse can be recognised from its melted or broken wire (see illustration). 6 To remove a fuse, first ensure that the relevant circuit is switched off. 7 Using the plastic tool clipped to the main fusebox lid, pull the fuse from its location. 8 Spare fuses are provided in the main fusebox. 9 Before renewing a blown fuse, trace and rectify the cause, and always use a fuse of the correct rating (fuse ratings are specified on the inside of the fusebox cover flap). Never substitute a fuse of a higher rating, or make temporary repairs using wire or metal foil; more serious damage, or even fire, could result. 10 Note that the fuses are colour-coded as follows. Refer to the wiring diagrams for details of the fuse ratings used and the circuits protected. Colour Rating Orange 5A Red 10A Blue 15A Yellow 20A Clear or White 25A Green 30A 11 The radio/cassette player fuse is located In the rear of the unit, and can be accessed after removing the radio/cassette player -refer to Section 12for greater detail.
Relays 12 A relay is an electncally-operated switch, which Is used for the following reasons: 4 A relay can switch a heavy current remotely from the circuit in which the current is flowing, therefore allowing the use of lighter-gauge wiring and switch contacts.
b)
A relay can receive more than one control input, unlike a mechanical switch. c) A relay can have a timer function - for example, the intermittent wiper relay. 13 The main and optional equipment relays are located in the main and auxiliary toseboxes (see Fuses). A number of additional relays may be fitted, depending on model and specification. These are generally mounted
3.5 A blown fuse can be recognised from its melted or broken wire adjacent lo the component being controlled; e.g. the radiator cooling fan relay(s) are mounted on a bracket next the cooling fan itself. 14 The direction Indicator/hazard warning flasher unit is mounted on the underside of the steering column slalk switch unit. It can be accessed by removing the steering column lower shroud panel (see illustration). 15 If a circuit or system controlled by a relay develops a fault, and the relay is suspect, operate the system. If the relay is functioning, it should be possible to hear it click as it is energised, if this is Ihe case, the fault lies with the components or wiring of the system. If the relay is not being energised, then either the relay is not receiving a main supply or a switching voltage, or the relay itself is faulty. Testing is by the substitution of a known good unit, but be careful - while some relays are identical in appearance and in operation, others look similar but perform different functions. 16 To remove a relay, first ensure that the relevant circuit is switched off. The relay can then simply be pulled out from the socket, and pushed back into position.
