Title: Electrical Problems
Post by: Enjoi on September 20, 2006, 08:39:37 AM

While driving the jeep this morning I noticed the check guages light came one, a quick scan of the insturment panel gave me a read of over 19 volts!! I quickly shut off the engine, waited a while, restarted and found the egngine running 12 volts again.

Is this a computer error? or do i have some sorta electrical problem somewhere?

I have Yellow Top battery, Mean Green Altenator, Pair of KC 100 watt slimlights, CB are the only electrical mods i have done to it.

Could have been a glitch but my other guess is the voltage regulator.

I think that some jeeps have the votage regulator built into the computer, I don't know what year models though. My jeep reads low voltage on the dash guage sometimes but when I check the alternator output with my voltmeter it's OK.

ive been away for a while and my dad took it 2 a local 4x4 shop (those bastards touching, violating her  :evil:) and there saying one of the battery cables is starting to corrode, makes since the increase in resistance would provide for more voltage

Hope that's all it is.  I had the same problem, and wasn't as forunate.  It was my PCM.

Hmmmm, I did not know this. I'll have to look into this and find out what years.
