I have been having battery/electrical issues lately. Jeep had 35k on it when I replaced with a new Duralast Gold battery last august, put new engine in at 40k in December, replaced with a Mopar battery in May when the Duralast went completely and utterly dead seemingly overnight. Month later that died too but was still jumpable. Dealer put a new Power Control Module in to fix the problem. 4 days later, dead. The wipers, warning lights all began flashing and then it died.
I have a Warn 9000i used winch, Rigid Dually's both installed myself. After the 2nd dead battery I took it to my 4x4 shop and had them re-install the wiring to make sure I didn't screw something up.
After my last dead battery on Wednesday night I could not jump it until I pulled the winch + light cables off the battery. Now the dealer is saying that the accessories are draining the battery and that I should just leave them off the battery until I need them then re-connect. Does this make ANY sense? The battery I put in last August was a Duralast Gold, which I thought was a good battery. The current battery is a Mopar battery, I'm not sure of the model as I just told the dealer to put it in so that it would be covered under warranty at the same place as my engine.
I'm at my wits end. My jeep has been in the shop almost every week for 2 months and this is several months after I had the entire engine replaced.
Is it for real that these batteries can't handle a winch and set of lights? This seems impossible. Is everyone else running dual batteries and I just happened to miss that?
Between dead batteries, thrown rods, warn out joints after 3k miles, sway bar and lockers that rarely disengage-re-engage and a host of other little problems I have no patience left in the tank. This is all inside of 12 months.
