I have a non-turbo, '90 T-Bird with a mere 76k miles, that has an
electrical problem: the battery keeps draining. If it is charged
while hooked up, the alternator actually gets warm, and the voltage
keeps dropping. I have used it for a couple short trips like this,
i.e., charging it while disconnected, then short drives where I leave
the engine running. I was thinking it was the alternator, as it seems
to be a bit noisier than normal.
However yesterday, even with a fully charged battery, plus a second
fully charged battery attached with jumpers, will not turn the engine
over (just get some anemic clicks). Also, a half-hour later, even the
dome lights won't come on.
Any clues as to what the problem might be? This has been an 'all of a
sudden' problem. Again, I was thinking alternator, but now I'm
thinking something else, maybe starter, that is mega-pulling current.
I read some post on here about the seat switches causing a problem
like this, but I've wiggled all those switches without a change.
