Chrysler Repair/2001 Town & Country: Battery drains overnight

I have a 1998 T & C and the battery would drain overnight. Replaced the altenator and problem solved. Found a mechanic that said 9 out of 10 times it's the altenator. Something inside altenator not shutting down completely.

Had problem your years. Very happy.

My 2001 T&C has the same problem.  3 private mechanics + 1 dealer mechanic cannot figure out the problem.  They claim they have tried identifying a fuse problem and can't.  Dealer replaced the PCM twice.  It takes months for the battery to drain, but once it does, I cannot go more than 24 to 36 hours without driving it, or the battery is completely dead.

Hi Elizabeth,

I can't answer you directly, you have to ask a new question for me to be able to do that. I suspect that you have a slightly higher than normal residual current that is there when the engine is shut off. That current is called the "ignition off draw" and it can be measured with an inexpensive volt-ohm-millamp meter. Once you verify that, then you can search for which circuit is drawing current beyond what it should and then identify what component is doing that. But unless you ask me a new question we can't dialogue about how to do this.
