CHARGING SYSTEM 6H-7
UNDERCHARGED BATTERY
This condition, as evidenced by slow cranking or indicator clear
with red dot can be caused by one or more of the following condi-
tions even though indicator lamp may be operating normal.
Following procedure also applies to cars with voltmeter and
ammeter.
Make sure that undercharged condition has not been caused
by accessories left on for extended period of time.
Check drive belt for proper tension.
If battery defect is suspected, refer to BATTERY section.
Inspect wiring for defects. Check all connections for tight-
ness and cleanliness, battery cable connections at battery,
starting motor and ignition ground cable.
NO-LOAD CHECK
1) Connect voltmeter and ammeter as shown in left figure.
2) Run engine from idling up to 2,000 rpm with all accessories
turned off and read meters.
If voltage is higher than standard value, check ground of
brushes.
If brushes are not grounded, replace IC regulator.
If voltage is lower than standard value, proceed to following
check.
