CAUTION
Obtain the code number and deactivate the audio anti-theft system before disconnecting the battery. (Refer to page T-113.)
Be sure the battery connections are not reversed because this will damage the rectifier.
Do not use high-voltage testers such as a megger because they will damage the rectifier.
Remember that battery voltage is always applied to the alternator B terminal.
Do not ground the L terminal while the engine is running.
Do not start the engine while the connector is disconnected from the L and S terminals.
SELF-DIAGNOSIS SYSTEM
The alternator has a self-diagnostic function to warn of problems in the charging system.
If any of the following problems arise, the alternator warning lamp illuminates.
1. S circuit open.
2. No voltage output.
3. Field circuit open.
4. B circuit open.
5. Voltage output too high.
