My car has a .005A (5mAmp) draw when off. It is on one of the fused wires going into the cab. If I take off wire A and leave on B, it goes to 0Amp. My question is this an issue? I know on modern cars there is as draw when off. But I would think a Maverick would be 0. I think its killing my battery. I dont start it more then once a month, but I always seem to be having a low battery.
