I have a 2005 Grand Limited with a key-of battery drain problem. Everthing functions fine, but when you turn the key off the drain through fuse 27 is almost 1 amp. It cycles from about .5 amp for 10 seconds then goes up to about 1 amp for 4 seconds then does it all over again. I can't find any spec, but I think this circuit should run closer to 0.01 amp with the key off. Any ideas?? Thanks--Steve in Iowa
I don't know what fuse 27 is exactly (I am in Oz and ours are quite different electrically), but I had a similar problem, took us a long time to find, and was eventually traced to a faulty rear seat roof mounted DVD player.
The Jeep is used on a regular basis. If it sits for 2-3 days the battery will be too low to crank. The battery has been replaced & kept charged. I think it has something to do with CAN (controller area network) not going into sleep mode. As much as I hate to do it, it looks like I'm going to have to take it to a dealer shop.
