Alright so now I've got a new problem.. I just got a brand new bigger battery with a higher crank voltage than the last battery so i thought that would fix the draining issue but it didn't. Checked the alternator with a voltmeter and it all checks out correctly. When the battery is fully charged the car doesn't have any problems starting, so i let it warm up, then turned it off, went inside for 30min, came back outside to start it up and the battery doesn't have enough juice to start the motor again. I cant point my finger on whats going on here now.. Alternator is fine and theres a bigger/better battery.. What else could it be?

do you know how to hook up a voltmeter in series? on the amp setting?
then you start pulling fuses till the draw goes away, look at that circuit.
remember, bad light bulbs (broken) or bad motors that have a short, can draw enough amps to not trip the fuse, but drain the battery

Yes i will try that out. Weirdly enough i got the car to start this morning and made it 20min away from my house and as soon as i got below 2k RPM the battery drained and the car died.sigpic
