Alternator question.... 200 1991

Sages,

So I've been working on my 1991 to get it back on the road and safe to drive, as it is going to become my daily driver here for the foreseeable future.

I get everything back together yesterday and my wife and I head out to dinner in it to meet up with some friends. No problems to dinner.

On the way back I fire up the car and I get the following lights on my dash board glowing dimly: service, battery, brake, brake failure and bulb failure.

The trip take about 30 minutes to get home, but I have no problem getting home. No dimming headlights, no nothing, just the dimly lit lights.

Once home I check the voltage both at the battery and at the alternator, and I'm getting 13.5 volts at both spots, so its charging, from what I can tell.

The alternator is freshly rebuilt and before the work on the car, on a cold start, I was getting 14.2 V as the alternator, and 13.8 at the battery, but since I did some work on the car, I cleaned up the connections between the battery, starter and alternator, and now I get the same everywhere so at least the gremlin has been killed.

However before the work, I was not getting any dimly lit lights.

So today, I took the alternator out and replaced it with another one that I had laying around.

When I started the car, turned the lights off, the same lights were still dimly lit, but eventually they went out. When I turned the lights on, the lights that were off, now came back on but dimly lit. I can turn the headlights on and off and get the dimly lit lights to come on and off.

I've done nothing else to the electrical side of the car while working on it except for cleaning up the connections from the battery to the starter and then to the alternator.

Any ideas on where to start looking to get rid of the dimly lit lights? Do I need to replace the alternator????

Thanks in advance,

Matt
