This should be a simple one for someone that knows these cars...
91 740 has been sitting for a while in the humid tropics - usually this means a myriad of electrical connection problems, and this has been no different. I had to hotwire the fuel pump relay because it was sticky; the car starts and runs but doesn't charge the battery.In addition, the alternator light doesn't ever come on - before car start (when all the other idiots lights show) or when it's running.
So, what should I check? there is a big wire and a little wire running to the alternator, but they disappear into wiring bundles. I'm assuming that one is for the light, and the other for the actual charging. Is there a ground cable as well?
I'm good with a voltmeter but I'm not sure what to test exactly. I could just throw another alternator in there, but I hate to spend $100 when it's just a corroded connection.
thanks in advance! elijah
