I had the red alternator light come on in my 89 westy yesterday, the light on the instrument cluster. I read thru some other threads and did some troubleshooting. Its not the blue wire or any other wire that is loose or corroded on the alternator itself, i checked and cleaned all the contacts.
The light does not change in intensity/flicker, and does not change with RPMs. The belt is fine, there is no slipping and everything is turning ok.
Is there anything else I can check before removing and taking the alternator to get it bench checked at the autoparts store?
Thanks,
Keith |

| You can test the voltage at the alternator. It should be at 14v. |

| If you're checking the voltage right after start-up -- blip the throttle to higher RPMs briefly before testing, else it will read low. |

Ok I will test he voltage at the alternator. Im assuming I test right at the main terminal on the alternator where the wires that run to the battery connect?
Thanks. |

Yes the big red wire on the back of the Alt is where you want to check. If you are in need of a new one, it is a great time to upgrade the bracket and wiring harness. I just went through the process.
