1989 Honda Accord Charging system

All the fuses are ok. I even checked for opens and shorts in the charge cable from the alt to the underhood fuse box. What should I have the computer checked for? Any specific problems? Could it be possible that Napa and autozone where wrong, and I should just buy a new alternator?

Have you managed to solve the problem?

I have done pretty much everything you have done and while I was trying to track down the problem, I accidentally left fuse # 1 under the dash out when I started the car. It ran for a little while and then died. I put the fuse back, started the car and had good voltage at the battery. I thought the problem was solved and ended up getting stranded by the side of the road the next day. For some reason, it went back to not charging. I tried pulling the fuse again today, this time with the car running, then just before it died, I plugged it back in and had good voltage again.

Does anyone have any idea how/why this is happening?

Thanks much!

BTW: My car is a carbureted 1989 Accord LX - Auto w/ 113,000 mi.

I did manage to fix the problem. Turns out Napa and Autozone were wrong and the alernator had a bad voltage regulator. A new alternator is $100, so I bought one from a junkyard for only $30, to see if it did need a new alternator and the old one was bad. It was a risk but it was worth it. Now it runs just fine.

Thanks for the advice, rasmataz, I will check the connectors and wiring again. I found a point where the white and blue wire coming from the voltage regulator (on the back of the alternator) goes to a harness and joins an almost identical white and blue wire that also comes from the engine somewhere, and I get a ground connection reading on that wire. The wire on the other side of the harness goes to the #1 fuse box, but I cannot figure out why there is a third wire involved - it does not appear on any of the schematics I have.

Toe-knee, thanks for letting me know what happened in your case. I have always suspected that it might just be that the bench test didn't catch the problem. If I can't find a problem with the wiring, I might just give it a try as well.
