Got a 97 gp gtp that engine and
supercharger run great, however I'm having
an electrical issue that my battery keeps
being drained to completely dead after 2 or
3 days. I have been through 4 batteries and
no one is able to figure out where the issue
is. We have also replaced the alternator, but
no success. Any ideas. Otherwise looking at
pulling the engine and getting rid of the
body.(which needs work also) just not sure if
I can get the 3800 sc engine in a 07 gp gt.
Since you have already replaced the alternator, you probably have a short to ground somewhere in the car. You should troubleshoot it by putting an ammeter in line with the positive battery cable and reading the current draw. I suspect you will notice that you are drawing battery current even though the car is not running. Now go to your fuse panel and begin removing one fuse at a time until the draw stops (ammeter goes to zero). You have now isolated the circuit to troubleshoot further. Good luck!
