My 91 with 159k, is having problems with the charging circuit. I can drive all day without lights or heater on, but when I turn the lights, front, and rear heater on, my voltage gauge drops and the truck eventually dies.
I have had an alternator go bad on an 85 4runner, and had the Christmas tree effect on the dash.
Has anyone ever had an alternator go bad without the dash lights all lighting up? The only light that stays on is the check engine light, but that stays on all the time. Brake, A/T temp, nor any other lights stay on.
Probably unrelated, I had to smack my started the other day because I had a stuck plunger, but I don't see how that would mess with the charging system.
One other thing I did try (I know it isn't a good thing to do) was removing the positive wire off the battery terminal and the truck died. In my limited knowledge, that was a good indication that the alternator was bad.
Do you all think that the alternator is bad like I do?
Thanks, Jason
