Battery drains while driving
Asked by tee87jay Dec 18, 2014 at 06:27 PM about the 1998 Dodge Durango SLT 4WD
Question type: Maintenance & Repair
I will charge my battery and over about 2 days of driving it will die. If i do not drive it then it is fine. My speedometer goes crazy all the time now and my gas gauge will mess up every now and then. I have replaced the battery and the altenator. the altenator is charging. Just need help trying to figure out what is slowly draining the battery while i drive?

There shouldn't be anything draining the battery while driving. I know you said it's a new alternator, but new parts are sometimes bad too. Sounds like the regulator may not be working correctly. Do you have a voltage reading on the cluster? With the car running it should be reading 12.5 ~ 13.5 volts under normal load. I would recommend having the alternator tested.
If your gauges are acting up especially the speedo. You might want to look at the pcm. I had a dodge van with the identical problem. Swapped the pcm and haven't had a prob since.
Yes the alternator has been tested and is charging also.

have the battery load tested when fully charged. if it shows 9 volts or less then the battery itself is bad.
