Electrical problem 87 300ZX

I was driving the car on the freeway when I noticed a slight miss. It was intermittent then got worse. After a few miles it began bucking. It seemed like it was not getting any spark as it would cut out then puff black smoke. After about 5 - 7 miles it got so bad I had to pull off. It stalled immediately and everything was dead. No power except for the power windows. I took it to a dealer and they told me it had a bad alternator. Up to that point, it showed no signs of a bad alternator. It cranked fine, no dead battery or slow cranking. I did notice about a week before that happened that all my indicator lights on the dash came on and stayed on....flickering occasionally. But the alt. light never came on by itself. The dealership would not do any work until they replaced the alternator. My concern is that there was some other electrical problem that caused the alternator to go bad and I am going to waste my money installing a new alternator. Questions: Couldn't they jump start the car with the bad alternator and troubleshoot it further? Would a bad alternator cause a car to just die like that without much warning? Has anyone experienced a similir problem and if so what was the solution? (I should also note that when the car was parked, I had to turn on my turn signal or the parking lights would come on.....seemed like an electrical problem somewhere.) I'd appreciate any advice. Thanks! Bob

Sounds likely.

Well that's what happens, one day they are working, the next they aren't.

That is EXACTLY what a bad alternator does on those cars, all the lights come on. When they all came on, what did you do about it?

Because it's the problem.

So your car has a normal problem and you are willing to spend money (at $75+ an hour) to search for a possibly non-existant problem? And you know they haven't done this already? I bet they have jumped it off and can see the alternator is dead so they called you up and told you what the problem is.

Yes.

See this all the time, it's a bad alternator.
