Hey guys, just got my Durango back from the trannie shop, the torque converter crashed, well since last Tuesday when we received the vehicle back, we now have another problem, thats the battery or the alternator.
Wednesday, the vehicle would not start, so I went and bought an new battery, since I replaced the alternator about 18 months ago, didn't think it was bad. After the new battery the car ran great, then Saturday morning, the car was as dead as a door nail. so I charged it for 5 hours.
The battery wouldn't even hold a charge, then I disconnected the battery from the system, the battery charged in about two hours, I think I have a serious drain on the system here, and i'm nto an expert.
First, this morning i'm taking the vehicle to the auto parts store to see if the alternator is bad, and if its now, I don't know where to go after that, thats why i'm posting in here.
Is there a possibility the transmission is causing a drain on the electrical system on this Durango, if so what could be the cause of the drain?

P.S I didn't have this problem with my truck before the transmission shop put their hands on it with the electrical issue!

 

They didn't hook something up right. I'd take it to the shop and tell them to fix it right!

 

What you have is a parasitic drain on the system. What you can do is read the electrical diagnosis and testing sticky if you don't know how to diagnose electrical issues. You need to disconnect the positive cable from the battery then hook the meter in series and set to amps. If it is above 10 amps you will blow a fuse but anything under that and you're good to go. There are a few things that always pull current so you are looking at a very small draw from these items (stereo, voltage regulator, and PCM are the main things) IIRC it is around 15 mA. If you have much more than that then you need to start pulling fuses one at a time until the source of the draw is determined. Once you find your draw find the reason why it is doing so.

 

thanks mean green, I was told how to do this today by a friend, gotta wait till our snow storm goes thru, my wife has to drive my plow truck and I can't make any money plowing with her driving the kids back and forth.
