Battery will not charge

I have a 95 jeep wrangler and all of the sudden my battery went dead and it will not hold charge I have purchased a new battery and the same thing happened. I jumped it and drove the Jeep home and it still did not take charge Any thoughts would be appreciated Help??????


Thanks

Jump it and take it down to Auto Zone or another parts store that does testing and have them check the alternator, but when you go in make sure you leave it running. :) One of my friends is having the same problem right now. ill let you know what he finds out....

Turn off the engine and measure the voltage at the battery. Should be about 12V.
Start the engine, make sure none of the accessories are on and measure the voltage. Should be 13-14V. If not then the alternator is dead.
Turn on the lights, radio, wipers, interior light,... Measure the voltage. It should be13-14. If not then the alternator is dead

HAHA, The guy I was talking about bought a walmart battery :lol: that was his only problem, the new battery was bad.

Sounds like it's the alternator for sure... Either that or there is a short, or something else constantly draining the battery. Just use a voltmeter to test like mentioned above to diagnose.

Chrysler has started putting the Voltage Regulator inside of the PCM.
This could be the problem, not the Alternator.
Have it checked with a scan tool.
If the field circuit is not switching the regulator circuit has failed.
