my 68 Firebird with a 400 engine drives me crazy. We were searching for a charging problem for almost 2 years. I had 2 alternators, 3 regulators and it was still not charging properly. I replaced the wiring from the alternator to the regulator and so on. Finally a mechanic changed it to a single wire alternator with an internal regulator. Then it worked. Now, without changing anything, the charging light went on and dimmed a bit when accelerating, but doesn't go off anymore.
I think, the alternator has a problem and I would like to replace it. But I have no idea, which one to take. And I cannot just go to a mechanic's, because I am in Germany and all the Mercedes, BMW and Porsche alternators won't fit.
Does anybody of you have a suggestion, what I could take or do?
