BATTERY/CHARGING SYSTEM
A frequently discharged battery is an indication that
it is deteriorated even if it proves normal in the
regulated voltage inspection.
The charging circuit may be abnormal if any of the
following symptoms is encountered:
1. Voltage not raised to regulated voltage (page
16-3)
• Open or shorted circuit in the charging system
wire harness or poorly connected connector
• Open or shorted of the alternator
• Faulty regulator/rectifier
2. Regulated voltage too high (page 16-4)
• Poorly grounded voltage regulator/rectifier
• Faulty battery
• Faulty regulator/rectifier
CURRENT LEAKAGE TEST
Remove the battery cover (page 16-5).
Turn the ignition switch OFF, and disconnect the
ground (-) cable from the battery.
Connect the ammeter
(+)
probe to the battery ground
cable and the ammeter (-) probe to the battery (-)
terminal.
With the ignition switch OFF, check for current
leakage.
NOTE:
• When measuring current using a tester, set it to a
high range, and then bring the range down to an
appropriate level. Current flow higher than the
range selected may blowout the fuse in the tester.
• While measuring current, do not turn the ignition
switch ON. A sudden surge of current may blow
out the fuse in the tester.
SPECIFIED CURRENT LEAKAGE: 1.0 rnA max.
If current leakage exceeds the specified value, a
shorted circuit is likely.
Locate the short by disconnecting connections one
by one and measuring the current.
