I have a 89 jeep wrangler and I cannot use my headlights, turn signals,
and stereo at the same time without my electric going crazy and
shutting off my engine.
With only the car on and stereo the
electric gauge reads about 14. I turn on the head lights and it goes
down to 10-11. When all three are on, it goes down to 8 and under then
the car starts to shake and dies. There is a brand new 140 amp
powermaster alternator and a new red top optima battery.
Thanks for your help!
Have you checked the tightness and/or tried replacing the alternator/drive belt? I have an 89 cherokee and I had the excat same problem .. I replaced my alternator drivebelt and wala .. fixed .. Crayz

i changed the battery and altenator in my truck - i get 14.3 volts at the battery when running and when using the accessories. But when i go in the vehicle all of the gauges go down when i turn on the accessories. they about bottom out.i hear the engine noise in my radio when i turn it on. and when i go over a bump all the gauges go crazy at the same time
