I posted this in the car electronics subforum, but didn't get a response.
A couple weeks ago my 88's battery died after replacing my A/C belt. It turned out that my alternator belt was loose, so I tightened it and charged the battery, but the problem remains.
Im not sure if it is a coincidence that this happened, or this set something off. I have no charge from the alternator and no battery light whatsoever on the cluster.
Here is what I've found
Exciter wire at alternator: 1.5v (I assume this is a result of some continuty between the power and exciter wire on the alternator because this remains even when the exciter wire is removed)
Pin 16 (blue wire) at blue connector on cluster (C1): 1.5v
Pin 14 (green wire) at blue connector on cluster(C1): no voltage
Pin 12 at diagnostic connector: 12.5v (huh?)
Pin 2 at distribution box connector (C200): 12.5v
What's confusing me is that there is power at the diagnostic connector but not at the connector in the cluster.. Doesn't it have to go through that first??
I also attempted to give the exciter direct power and this turned on the battery light only when the key was off, but once the key was on, the light was gone and there was still no charging once the car was started.
BTW I replaced the alternator right after this problem began with one I had laying around off a blown motor (not 100% sure if it's functioning).
I'm a little bit stuck at this point!! Whoever has the knowlege to tell me why there's no voltage at C1, but voltage at the diagnostic plug, you're input is greatly appreciated!
Thank you!
