refer to Section 6 of the Chassis Overhaul Manual.

Because of the interchangeability and similarity of

many engines, engine sub-assemblies and engine parts,

regardless of which passenger vehicle they are used in,

typical illustrations and procedures are used except
where specific illustrations or procedures are necessary

to clarify the operation. Although illustrations showing

bench operations are used, most single operations, when

not part of a general overhaul, should be performed (if

practical) with the engine in the vehicle.

circuit. Make absolutely certain all connections in

the circuit are secure.

5.
Do not short across or ground any of the terminals

on the generator or regulator.

6. Do not attempt to polarize the generator.

7.
Do not disconnect lead at generator without first dis-

connecting battery ground cable.

Trouble in the A.C. charging system will usually be

indicated by one or more of the following conditions:

1.
Faulty indicator lamp or ammeter operation.

2.
An undercharged battery (usually evidenced by slow

cranking speeds).

3.
An overcharged battery (usually evidenced by exces-

sive battery water usage).

4.
Excessive generator noise or vibration.

Described below are a series of on-the-vehicle quick

checks which are designed to assist the service tech-

nician in locating troubles within the various components

of the engine electrical system. Additional checks, ad-

justments and overhaul procedures of these components

are also described in the "Charging Systems—Service

Operations Section" and should be referred to as

necessary.

STATIC CHECKS

Before making any electrical checks, perform the fol-

lowing static checks:

1.
Check for loose fan belt.

2.
Check for defective battery. (Refer to Battery).

3.
Inspect all connections, including the slip-on con-

nectors at the regulator and Delcotron.

NOTE: Do not short field to ground to check if

generator is charging since this will seriously

damage the charging system.

SYSTEM CONDITION TEST

This test is used .to indicate the overall condition of the

charging system (both good and defective) and to isolate

the malfunctioning unit if the system is defective.

NOTE: On Corvette models difficulty may be

encountered -when attempting to make the re-
quired test connections at the voltage regulator.

It is advisable to remove the regulator from its

mounting location to perform the necessary con-

nections at the regulator for the following tests

but make sure unit is grounded.

1.
With ignition off, perform the prescribed Static

Checks outlined in this section. Then set hand brake

and shift transmission
into
neutral.

2.
Connect a voltmeter from junction block relay to

ground at regulator base.

CAUTION: Be sure meter clip does not touch a

resistor or terminal extension under regulator,

3.
Connect a tachometer on engine.

4.
Models equipped with Indicator Lamp: Turn ignition

switch on "ON" position and check indicator lamp.

If lamp fails to glow, perform appropriate tests and

corrections (Indicator Lamp Circuit Tests) before

continuing.

Models equipped with Ammeter: Turn ignition

switch to "ACC" with an accessory on and check

ammeter. If ammeter fails to read discharge, check

ammeter circuit before continuing.

5.
Models equipped with Indicator Lamp: If lamp glows,

start the engine and run' it at 1500 rpm or above.

Check indicator lamp. If lamp fails to go out, per-

form appropriate test and corrections (Indicator

Lamp Circuit Test) before continuing.

Models equipped with Ammeter: If ammeter reads

discharge, start the engine and observe ammeter. If

meter fails to move toward charge (from original

position), perform appropriate test and corrections

(Field Circuit Tests) before continuing.

NOTE: At this point a field circuit has been

established and any other problem will lie in

generator or regulator.

6. Turn on high-beam headlights and heater blower

motor to high speed, run engine at or above 1500

rpm (for a few minutes, if necessary) and read the

voltage on meter.
