CHARGING SYSTEM INSPECTION
CURRENT LEAKAGE INSPECTION
Remove the seat (page 3-3).
Disconnect the negative (-) cable from the battery.
Connect the ammeter
(+)
probe to th e negative H
cable and ammeter H probe to the battery H termi-
nal.
Check for cu rrent leakage.
NOTE :
When measuring current using a tester, set it to a
high range, and then bring the range d own to an
appropriate level. Current flow higher than the
range selected
may
blow the fuse in the tester.
SPECIFIED CURREN T LEAKAGE: 0.1 rnA m ax.
If
cu rrent
leakage exceeds the specified value, a
short ed circu it is likely.
locate the short by disconnecting connections one
by one and measuri ng the current.
CHARGING VOLTAGE INSPECTION
Be sur e the battery is in good condition before per-
forming this test.
Warm up the engine to normal operating tempera-
tu re.
Connect the multi meter between the battery posi-
tive (+1 and negative (-) terminals.
NOTE:
To prevent a short, make absolutely certain which
are the positive (+1 and negative (-) terminals or
cables.
Measure the voltage on the multi meter w hen the
engine runs at 5,000 rpm.
Sta ndard:
