Been lurking this board since bought my used 96 in Jan. - that's long enough that I know to use the search button. Many thanks for all who contribute - I now know enough to make me dangerous with Prev maint.
Here's my problem: My alternator light comes on intermittently for short periods of time. Usually turning on/off some switch will trigger the light to come on/go off (i.e. rear heater, hazards, blinkers, sunroof, windows, shifting transm, etc). However, there is no pattern or consistency to what makes it come on.
When it is on, sometimes everything electrical goes dead (radio, climate, instrument cluster) - much like what would happen when starting the engine (causes tranny to not shift into OD). At other times, the alt light is on, and everything else is fine - all electricals working. Other weird things happening are: 1) turning key to start infrequently takes a few seconds for starter to engage (happened maybe 3 times) 2) New today is engine will crank, but not start (no elec/ignition?) Funny thing is I took out my key flipped it over and it started just fine (coincidence?)
I tried taking it to dealer while it was acting up, and of course the light went off. They did test it and said alternator is OK. Service rep's speculated alternator was on it's way out or "tumblers" (?) associated with key/ignition system.
Do I have a short or is alternator dying? If it's a short, any suggestions on how to isolate it?
