How much current should be drawn when car is "off"?
I've got a battery drain problem, after one day it's a bit sluggish turning over, leave it for three days and it won't start. I fitted a new stereo a few weeks ago, this has an amplified DAB arial. Originally I wired this incorrectly so it was connected to the "always on" power lead rather than the switched power lead so this flattened the battery about 3 times, I've resolved this now. I've already swapped the wires in the little white box so the stereo turns off when ignition is off. This improved things but it's still draining.
THe charging system seems to be working fine, giving 13.7 volts when the engine is at tickover and the battery is fully charged after a run. I've disconnected the battery and left it for nearly a week and it was still showing a full 12 volts. I checked the current being drawn at the battery and it's 0.07 amps, 70 milliamps, is this too much? I also disconnected the stereo altogether - no difference, disconnected the alarm - dropped to 0.06 amps, so I don't think the problem's there.
I'm about to go out and start taking out fuses but the question is... is 0.07amps normal drain? And the battery is about 2 years old with a four year guarantee but has now been drained several times, it's not losing charge when disconnected but could there be a problem there?
Any help would be very helpful! Thanks
