My Pacifica Eats Car Batteries - Chrysler Forum

minvi · #1 07-16-2011, 02:57 PM

Has anyone else observed this?

Our '04 Pacifica will go through new car batteries at the rate of about 1/yr.

I cheked for large current draws and didn't find anything serious.

I also got the alternator tested at a car parts store and it passed with flying colors.

Anybody else have the same symptoms or cure?

Thanks,
Tim

Yes. My 04 will drain a battery in 10-15 minutes if I leave the liftgate up with the radio on. I go to crank it up and its all clicks...gotta jump it off. I haven't done any troubleshooting myself, but that was the route that I was going...searching for some random current draw. I've just been ovbservant enough not to leave accessories on for too long with the gate up. Hopefully we can find a tip or two here.

I upgraded my grounds and alternator + and ground wires to a larger AWG wire... and I still have my original OEM batter in my 05.

A novel idea madman, I've had to do that on other cars in the past, but for other reasons. What prompted you to automatically upgrade? What size altenator?

I didnt upgrade the alternator itself, just the wiring, the oem wiring is too small. And the Pacifica is a very electronically needy car..

Ok, got it. That is the tip of the day for me.
Thanks mustardmadman.
