Re: power draw on 2004 grand cherokee limited

Hi V8PLUS, i had seen your thread about the battery drain, but donīt know where to install a charger, so i didnīt reply.
The IOD fuse is at position 15 (50A) of the Power Distribution Center under the hood. Removing that fuse will NOT completely stop all battery drain, but at least most of it (by removing the power to several memory functions of TCM, clock and a few more). When not using your car for 30 days or more, its even better to disconnect the negative lead from the battery, to stop all external drain.
That said, a battery will drain its energy even when its completely disconnected from any circuit. Seems that a healthy battery is discharging 2 % of its capacity a day (older batteries or when in bad shape even more). A rule of thumb is to charge a battery at least every 30 days. (a 60 % discharged battery can be considered as fully discharged) The problem of a fully discharged battery is that an irreversable chemical reaction inside the battery occurs, that reduces its capacity and finally destroys it completely.

Re: power draw on 2004 grand cherokee limited

Thats where weīre here for and yes, iīm a trained mechanic, only for the brands Boeing and Airbus .
My jeep is my hobby and i do all the maintenance on it myself (except the tranny rebuild last year, which i finally preferred to have done myself), so i try to learn as much as possible with the help of my service manual, the Google search function and last but not least, our great forum.
