I've got a '98 D with the 318ci in it. I bought it about a year ago and ever since then especially in cold weather, if I let it sit for a day or two without driving it, it won't start and I need a jump. So far, I've had the mechanic do a draw test to see if anything is drawing current, he said no. I've tried two different batteries from two different stores and two different brands.
A guy told me something about a diode in the alternator that will draw current with the engine off, something like a flash diode I believe he said. Does anyone know what it could be.
BTW...I took the cable off the battery and the truck still ran. I have to give the kids a ride to school in the morning here in Wisconsin, it's cold as hell and the problem is getting worse.

I'd have the alternator checked. it is possible for one of the alternator phases to go bad. the remaining two will run the vehicle, but limit output so that there's nothing left to charge the batt, especially when you have to run lights, wipers, heater blower, rear defrost , etc on those cold winter mornings, thus slowly draining your batt.
also make sure you have good, tight, corrosion free connections everywhere.
I don't use the remote key locker or the lock all button inside the cab....I manually push down the locks then close the doors. This prevents the alarm from activating...at least the security light doesn't come on, so it looks as tho it's working. I then use the key to open the driver's door.
Well...I'll have to wait until I don't use the truck for a day....which shouldn't be long. I don't do that much driving since my back went out. I'll let u know what happens after it sits...but so far it's been starting up with no probs.
I am having the same problem... I let my truck sit from last night at about 5pm till now and its 3pm the next day and the batt is dead... IDK what the hell is going on... Ive tried to do everything. Im bringing it into the shop now.... This needs to get worked out cuz i need it to be dependable and plus a have a Brush Guard and 4 Foglights on there way so i need the electric system to be strong.
Hey, Got some news for ya. Got my D back from the guy at the shop today. It was a short in the electrical system. He never told me exactly where but it was a short somewhere... Who knows. If your somewhat savy with tools, grab your self a voltameter a pair of dykes and some electrical tape and get crackin. Try to isolate which circuit is drawing. What you can do it do a test on each of the main circuits when the truck is off and see where you could be loosing power. If youve tested all the main ones id just bring her in. Shes your D and she deserves a good fix. Haha. Well hope ive helped. Good Luck
Mine's been in the shop since yesterday (Thursday), hopefully they will call today with some kind of solution. I'll ask them exactly where it was, maybe it can help someone else. BTW...I cannot post using firefox...only IE...
Good luck with finding your problem as far as posting on firefox I would do a search in the tech support section and if nothing else put a post up some of our guys on here know the answers to those types of problems.

00 Durango 5.9L SLT
I've got a few things done
I have a 99 Durango. New off the show room floor. I am on my 5th Battery. The last 4 just failed. No questions, buy a new batt. I am beginning to have problems with my present batt. It has died twice in the last month. Both times I have taken it in, got it charged and they tell me there is nothing wrong with the batt. Down to the Batt exchange, they check the elec sys free. Says there is nothing wrong with the altenator or EVR. I put an amp meter on the ground of the batt, showed 8 milliamps, well within the range. Now what.
This afternoon, I got home and thought I would have a look see at a couple of things. When I parked the Durango in the garage, for some reason I put it in park and applied the parking brake. When I went back out, about 30 mins, I notice the Brake light was dim... and the four gages, fuel, voltage, heat and oil press were moving up slowly and then dropping off. I sat there looking at these movements and brake light sort of amazed. The key was not in the ignition. How could this be happening. I started the engine, turned it off and still the same movements and light. Took off the parking brake, light went out but movement of the instruments continued. Now knowing what was going on or what to do, I turned the radio on, turned the head lights on, nada. Then I turned the AC/heating switch on and it stopped. I could not duplicate the action with the AC/heating sw in the on position. I turned it off and could duplicate the brake light and movement of the gages. I got to thinking about the two days the thing had died. I had driven somewhere early in the morning and turned off the AC/heating(I live in AZ) and had not turned it back on. The vehicle had sat for about 8 hours before I got back in it and found the batt dead. I can duplicate this problem, but my mind asks. what connection does the AC/heating switch have with the instrument cluster and why would it be coming on and shutting off. Don't know. But I'll bet is is one of those cheap parts like the CTM or PCM,.
My present solution: Don't shut engine off with AC/heat switch in off position.
