Troubleshooting

Step	Action	Yes	No
1	Check accessories which use excessive amounts of electricity. Are accessories being installed?	Remove accessories.	Go to step 2.
2	Check the battery for current leakage. Refer to “battery current leakage inspection” . Is the battery for current leakage ok?	Go to step 3.	Short circuit of wire harness. Faulty electrical equipment
3	Measure the regulated voltage between the battery terminals. Refer to “regulated voltage inspection” (page 1j- 3). Is the regulated voltage ok?	Faulty battery. Abnormal driving condition.	Go to step 4.
4	Measure the resistance of the generator coil. Refer to “generator inspection” . Is the resistance of generator coil ok?	Go to step 5.	Faulty generator coil. Disconnected lead wires.
5	Measure the generator no-load performance. Refer to “generator inspection” . Is the generator no-load performance ok?	Go to step 6.	Faulty generator
6	Inspect the regulator/rectifier. Refer to “regulator / rectifier inspection” . Is the regulator/rectifier ok?	Go to step 7.	Faulty regulator/rectifier
