INSPECTION
BATTERY CURRENT LEAKAGE
• Remove the right frame cover. (8-3)
• Turn the ignition switch OFF.
• Disconnect the battery - lead wire.
• Measure the current between - battery terminal and the -
battery 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)

YES Go to Step 6.
NO Faulty generator
YES Go to Step 7.
NO Faulty regulator/rectifier
YES Faulty battery
NO
• Short circuit of wire harness
• Poor contact of couplers
* In case of a large current leak, turn the tester to high
range first to avoid tester damage.
* Do not turn the ignition switch ON when measuring
