Battery Drain Problem Solved

Hello all,

My 2005 GT started the mysterious battery drain problem last week. I went through 2 new batteries in a week. After spending hours on the net searching everything possible I found out the hard way. After washing the car I noticed water on the passenger floor that led to a plugged cowl drain. This got the sjb unit soaked & started causing shorts. Lucky for me my mechanic had a 2005 wreck & we swapped it. So far so good with no parasitic draw. Now I will make sure the cowl drain stays open.

I hope this helps anyone having this issue.

While this may sound ignorant ..... may I ask what is a "sjb unit"?

It is the smart junction box located behind the passenger side kick plate. If you get a severe cowl drain plug the water can cause all sorts of problems if it gets in there.
