HELP its my DD!!

what amperage is your altenator? thats a lot of load on the stock alt. does your jeep have a volt gauge?

oops forgot to mention that...... its at 14 when idling with standard stuff like headlights, fogs, stereo quietly on, and heater. leading to my guess that the alternator is good and the battery just cant take the extra load as it surpasses the alternator's capacity!

how old is your battery? you can have it tested at most auto parts stores for free.

I recommend and exspecially for a daily driver like mine and optima yellow top. Try to get a deal because there a little pricey.

your symptoms from your first post are most likely the alternator. the alternator is a direct connect to the battery, and pops straight from there to the wiring harness on renix, or fuse box on H.O.


even a bad battery shouldn't affect a vehicle that is already running. it *could* give you dim lights etc. but if your car is gonna die, it's more serious than just a battery.


this is just my experience.

'97 and '98 are the only years that work on yours. '96 and older don't, '99 and newer don't.
