INSPECTION

BATTERY CURRENT LEAKAGE
• Remove the seat. (8-3)
• Turn the ignition switch to the OFF position.
• Disconnect the battery - lead wire.
Measure the current between - battery terminal and the - bat-
tery lead wire using the multi circuit tester. If the reading
exceeds the specified value, leakage is evident.
 Battery current (leak): Under 1 mA
 09900-25008: Multi circuit tester set
 Tester knob indication: Current (, 20 mA)

* Because the current leak might be large, turn the
tester to high range first to avoid tester damage.
* Do not turn the ignition switch to the "ON" position
when measuring current.
When checking for excessive current leakage, remove the cou-
plers and connectors, one by one, so as to locate the position of
trouble.
