My battery has been draining down pretty badly lately and I checked for parasitic draw and got between 4.5A and 5.5A. Disconnected amp power cables and pulled the fuses for my headlight wiring harnesses and saw no change. Before I start ripping things apart, can anyone tell me what some common causes are?
And here I was excited to take it up to BIR for CRA weekend. I havent driven it up there all year because Im usually racing so I ride in a van. This month im somewhat crippled so Im just working. Anyway...
Common parasitic draws?

Monitor the amp draw and pull one fuse at a time to isolate which circuit it is.

This answer is a PITA!!
Figured Id drop it out there over the weekend and see if anyone had a good place to start. Even once I find the circuit, its not likely to be obvious...
Fans arent running, btw.
I'll have to start at it tomorrow. Thx guys.

The fans don't have to run to be a parasitic draw. My work van's relay was stuck closed and would kill the battery overnight and there was no outward signs.

Will check as soon as I replace the fuse in my multimeter.
The battery doesnt seem to want to take a charge, either. I drove to work with everything off and disconnected it when i shut off the car, but it still wouldnt start. Its also taking a really long time to start when I do have the power to crank it properly. Not sure if its related or just a coincidental misfortune.

Re: 02 with 5+ amp parasitic draw.
A failed diode in the alternator can cause this problem so you want to have the alternator checked.
