Electrical problem Sign In

I drive a 1996 Chief Cherokee Laredo & I`m having weird electrical problems.Dash board indicators will come even when I don`t have a problem.Sometimes the interior lights will come on by themselves & sometimes I can hear my door lock open & close periodically.Now my oil gauge doesn`t work.I know my alternator is having problems as it shows a fail on the meter but the battery is fine.Would the alternator be the source of all these problems? I`m getting the alternator replaced tomorrow & I`m really praying that it`s the source of my other problems.Can you advise me on this?
Thanks

What voltage do you read with engine running for alternator?

Other wild guesses are an alarm gone wild, buttons on door panel got soaked, wires in door jam may be shorted. Oil pressure alone not working is probably sender wire with a poor connection on the engine.

If remote for opening doors is all mixed up that could explain interior lights AND door locks going nuts,

Re: Electrical problem Sign In

The question you asked I have no answer.A friend tested the battery & alternator for me.The battery passed but showed a fault in my alternator.Are you suggesting that possibly the problems I`m having are being caused by a short in the door?

Re: Electrical problem Sign In

Alternator could be checked off vehicle and this may be one that the body control module regulates the output - nasty expense possible if so. It may be capable of working but only partially.

Unless wiring all over the place is hacked up I don't know how that relates to power locks, or interior lights?

A long stretch is that somehow wires going thru a rubber snorkel in usually driver's door jam are messed up and if lights stay on or a short there funky things can happen, drain the battery perhaps which in turn can be real hard on the alternator to charge back up or kill it.

Just start hunting for things out of line if lucky enough to see a flaw somewhere?
