No problem!  Do you have a aftermarket deck/Amplifier?  i would suspect those.

Both.
I'll have to check both.

Went to start it this morning and still needed a jump though. How long does it take an alt to fully charge a batt? Ran it for probably half hour last night.

A half hour should be enough to charge it up so it will start itself after you shut it off.

A 40mA draw is still kinda high, I would like to see no more than 25mA.   Does that car have a alarm aswell?

If you have a normal size battery it will take about 8 hours to fully charge a battery on a small 10amp charger.   If you doing quick stop and goes with your car, the battery never gets fully charged back up from the alt.    There just not enough run time.

So even with that fuse pulled, it was still dead this morning.
Jumped it and left the negative terminal off this time when I parked.

I believe I found the problem with my oil pressure gauge, so fingers crossed it starts tomorrow fine!!
