URGING SYSTEM

LEAKAGE CURRENT INSPECTION

Check the battery for ampere leakage before making an charg-
ing output inspection.
Turn the ignition switch OFF. Remove the negative cable from
the battery.
Connect ammeter between the negative cable and battery
negative (-) terminal,
The ammeter should indicate below 1 mA with the ignition
switch OFF.

REGULATED VOLTAGE INSPECTION

• order to obtain accurate test readings when checking the
merging system, the battery must be fully charged and in
condition before performing this test.
/'" the engine must be running to do some work, make sure the
area is well-ventilated. Never run the engine in an enclosed
area. The exhaust contains posisonous carbon monoxide gas
that can cause loss of consciousness and may lead to death.
Warm up the engine to normal operating temperature,
Stoр the engine, and connect the voltmeter as shown,
Connect the tachometer and restart the engine,
Allow the engine to idle, and increase the engine speed gradually
The voltage should be controlled to 13.5—15.5 V at 5,000
rpm. If it is not; check the regulator/rectifier.
DAUTION
• Be careful not to allow the battery positive cable to touch the
frame while testing.
ALTERNATOR
NOTE
• It is not necessary to remove the stator coil to make this
test.
INSPECTION
Disconnect the regulator/rectifier {alternator) 3P connector.
Check the resistance between the connector terminals.
STANDARD: 0 . 1 - 1 . 0 Q (at 20°C/68°F)
Check for continuity between the connector terminals and
ground. There should be no continuity.
Replace the alternator stator if readings are far beyond the
standard, or if any wire has continuity to ground. Refer to sec-
tion 8 for stator removal.
