1999 HONDA CIVIC connection

-Performance Test
NOTE: Before staning the following checks. disconnect
the wire from terminal M. and make a connection as
described below using as heavy a wire as possible (prefer-
ably equivalent to the wire used for the car).
Pull-in CoilTest:
Connect the battery as shown, lf the staner pinion pops
out. it is working proPerly.
CAUTION: Do not leavo tho batterv connost€d for more
than 10 seconds.
Hold-in Coil Test:
Disconnect the battery from the M terminal' lf the pinion
does not retract, the hold-in coil is working properly.
CAUTION: Do not loavc lhe battsry connected for mot6
than 10 ssconds.
Retracting Tosi:
Disconnect the battery also from the body. lf the pinion
retracts immediately, it is working properly.
GAUTION: Do not loave the baftery conn€ctod tor more
than 10 seconds.
Startor No-load Tost:
Clamp the starter firmly in a vise.
Connect the starter to the battery as described in
the diagram below, and confirm that the motor
starts and keeps rotating.

Charging System
Rectifier Removal (cont'd)
Separate the rear housing from the stator/rectifier
assembly by removing the four screws and the ter-minal nut.
TERMINAL NUT
Unsolder the rectifier from the stator leads,. To avoid damaging the diodes with heat, pinch
the stator leads between pliers to carry heat off,and apply the soldering iron only long enough toseparate the leads from the rectifier.. Use a 100 W soldering iron.
STATOR SOLDERING
7. Install the new rectifier in the reverse order of removal.. Apply the soldering iron only long enough toensure a good connection so the heat will notdamage the diodes.
a Use only a rosin core type solder or solder joints
will corrode.

Rectifier Test
NOTE: The diodes are designed to allow current to pass
in one direction while blocking it in the opposite direc-tion. Since the alternator rectifier is made up of ninediodes, each diode must be tested for continuity in bothdirections with an ohmmeter that has diode checkinocapability; a total of 18 checks.
1. Check for continuity in each direction between- the B and P terminals.- the B'and P terminals.- E {ground) and the P terminals.
All diodes should have continuity in only one direc-UOn.
lf any of the diodes fails, replace the rectifier assem-bly, (Diodes are not available separately.)

Switches
These switches move
together; the broken straight
line between them means the,
are mechanically connected.
Other types of switches are
controlled by a coil or a solid
state circuit. Unless otherwise
noted. all switches are shown
in their normal (rest) position,
with power off.
This ground symbol (dot
and 3 lines) overlapping the
component means the housing
of the component is grounded
to the car frame or to a metal
part connected to the frame.
This symbol represents
the bus inside a ground
connector. The dots I

The ground symbol (large dot)

bus and metal (grounded) part
of the car.

Current rating
Diodes
A rectifier diode works like a one
way valve. lt allows current to
llow only in the direction of the
arrow.
A Zener diode blocks reverse
current at normal voltages just like
a rectifier diode. At high voltages.
however, a Zener diode allows
current to f low in reverse
oo
Each "T" lerminal (ring type)
is numbered for reference and
location. A "T" terminal is
secured with a screw or bolt.
Shielding
This represents RFI
(Radio Frequency
Interference) shielding
around a wire. The
shielding is always
connected to ground.

T

In the "OHMS" range, the DVOM will measure
resistance between two points along a circuit.
Low resistance means good continuity.
Diodes and solid-state devices in a circuit can
make a DVOM give a false reading. To check
a reading, reverse the leads, and take a
second reading. lf the readings differ, the
component is affecting lhe measurement.
Jumper Wire
Use a jumper wire to bypass an open circuit.
A iumper wire is made up ot an in-line fuse
holder connected to a set of test leads. lt
should have a five amoere fuse. Never
connect a jumper wire across a short circuit.
The direct battery short will blow the fuse.
Short Finder (Short Circuit Locater)
Short finders are available to locale shorts to
ground. The short tinder creates a pulsing
magnetic field in the shorted circuit whlch you
can follow to the location of the short. lts use
is explained on page 15.
SHORT FINDER
To ordei any test equipment shown above,
contact your local tool supplier. For a list of
suppliers and tool numbers, refer to Honda
Required Special Tools and Equipment
Service Bulletin.

Troubleshooting Precautions
Before Troubleshooting
1. Check the main fuse and the fuse box.
2. Check the battery for damage, state of
charge, and clean and tight connections.
CAUTION:
. Do not quick-charge a battery unlers
the battery ground cable has been
disconnected, or you will damage the
alternator diodes.
. Do not attempt to crank the engine wlth
the ground cable disconnected or you
will severely damage the wiring.
While You're Working
1. Make sure connectors are clean, and have
no loose terminals or receptacles.
2. Make sure lhat connectors without wire
seals are packed with dielectric (silicone)
grease. Part Number: 08798-9001 .
Pack wllh dlelectrlc (sillcons) greass
When connecting a connector, push it until it"clicks" into place.
Do not pull on the wires when
disconnecting a connector. Pull
only on the connector houslngs.
Most circuits Include solid-state
devlces. Test the voltages In these
circuits only with a lo-megaohm or
higher impedance digital multlm6ter.
Never use a test light or analog meter
on chcuits that contain solld-state
devices. Damage to the devices
may result.
