hey guys,
a few weeks ago on my 89 SC my battery/alternator light started coming on at seemingly random times, often blinking and with no real pattern. So i took it into the shop and they tested the alternator and battery with load etc. and showed me the readings and everything tested good they said, no sign of the alternator going, and the battery is quite new and that was good.
so that made me feel better, but since then, the light has continued to come on a fair amount, and it's just seemingly random. I read that if the light comes on when idling and you rev the car and it goes off, it's the alternator, and vice versa for the battery. but sometimes that's what the light does, but other times it'll be flashing on and off during high revs...so who knows. About the only thing that's constant is that when the light comes on, the dash lights dim a bit. Other than that, the pattern is seemingly random, and the stereo/fan being on or off doesn't effect it, only revving the car seems to, but that's not constant either like i said above.
so anyways, i'm worried that the alternator is starting to go or something and i'll be driving one day and the car will die, even though everything tested ok. Any ideas as to what could be causing this?
Thanks in advance for any feedback....everyone here is a big help whenever I post....thanks a lot!!
