CHARGING SYSTEM INSPECTION

CURRENT LEAKAGE TEST

Turn the ignition switch
ative
Connect the ammeter
cable and the ammeter
minal.
With the ignition switch OFF, check for current leak-
age.
NOTE:
SPECIFIED CURRENT LEAKAGE: 0.1 mA 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.

CHARGING VOLTAGE INSPECTION

If the engine must be running t o do some work,
make sure the area is well ventilated. Never run the
engine in an enclosed area. The exhaust contains
poisonous carbon monoxide gas that may cause loss
of consciousness and may lead t o death. Run the
engine in an open area or with an exhaust evacua-

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 blow out 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.
To prevent short, make absolutely certain which
are the positive and negative terminals or cable.
