Ok first off.
Optima red top battery (6 months old) w/clean terminals
Big 3 upgrade + Alt rewire
Cleaned up all grounds
higher output alternator (4 months old)
I do have a aftermarket stereo (pioneer, nothing fancy) and an amp and sub w/capicator
HID's fog and headlight
I also have a radar detector that stays on for 6 hours before it auto turns off. So I usually just leave it plugged in.
Now onto the problem. For the last couple weeks if I let my grand prix sit for more then 1 day without starting it, it either wont start (barely turn over) or struggle to turn over. Mind you its Wisconsin so its getting down into the teens or colder at night.
I don't get it. Its like there is a draw somewhere. So, I grabbed my test light and disconnected the negative battery terminal. I then hooked up the ground on the test light and put the probe on the positive terminal, no light what so ever. Not even a little dim. So I'm guessing there isn't a power draw going on somewhere, otherwise the light would come on.
So why on earth is this happening? I'm currently charging my battery with my charger. The volts were low, but not completely dead.
It makes no sense to me ! New alt, New battery, wiring is all top notch, no draw (at least I think),
Anyone have any suggestions?
