PREPARATION
CONDITIONS FOR THE TEST
RESULT
- "New belt" refers to a belt which has been used less than 5 minutes on a running engine.
- "Used belt" refers to a belt which has been used on a running engine for 5 minutes or more.
- After installing a belt, check that it fits properly in the ribbed grooves.
- Check with your hand to confirm that the belt has not slipped out of the groove on the bottom of the pulley.
- After installing a new belt, run the engine for about 5 minutes and recheck the belt tension.
VISUALLY CHECK GENERATOR WIRING AND LISTEN FOR ABNORMAL NOISES
1. Check that the wiring is in good condition.
2. Check that there is no abnormal noise from the generator while the engine is running.
CHECK DISCHARGE WARNING LIGHT CIRCUIT
1. Warm up the engine and then turn it off.
2. Turn off all accessories.
3. Turn the ignition switch "ON". Check that the discharge warning light is lit.
4. Start the engine. Check that the light goes off.
INSPECT CHARGING SYSTEM
1. Turn the ignition switch to "OFF".
To find abnormal conditions of the connection, actions should not be taken on the two terminals and each connection
during the test.
2. Connect a digital voltmeter between the generator "B" terminal and battery (+) lead wire to the battery (+) terminal. Connect
the (+) lead wire of the voltmeter to the "B" terminal and the (-) lead wire to the battery (+) terminal.
1. Start the engine.
2. Switch on the headlamps, blower motor and so on. And then, read the voltmeter under this condition.
1. The voltmeter may indicate the standard value.
0.2V max.
2. If the value of the voltmeter is higher than expected (above 0.2V max.), poor wiring is suspected. In this case check the
wiring from the generator "B" terminal to the fusible link to the battery (+) terminal. Check for loose connections, color
change due to an overheated harness, etc. Correct them before testing again.
