default current draw on battery

Hello, what should the current draw on the battery be when everything is shut off? I'm measuring a 13 ma draw at the battery. I'm going to try to narrow it down by pulling fuses one at a time, but thought I'd ask first what would be the normal draw with nothing on, key out.

Re: default current draw on battery

On older cars like ours, 25-50 mA is acceptable. Keeping the memory pre-sets and the clock and alarm are the only things that continue to draw current when the ignition is off.

Newer cars have a limit of between 50-85mA because they may have more electronics, such as memory seatings for seats and mirrors, etc.

Anything over 100mA indicates a parasitic draw or electrical issue that needs to be addressed

Excellent. Thanks SVXCESS. So 13 mA is nothing to worry about ! That saves me the time I would have spent trying to hunt it down.
