Re: long time no post, Urgent charging system question
Not sure about the 4.78 ma drain. Glad to hear you found the major problem and corrected it. If your alternator is like mine, there are essentially two "circuits", one that is always live on battery, that's the thicker red wire, and a smaller (looks black on mine) that only gets power with the ignition on. I assume the wire that is drawing power with the ignition off, is the thicker red wire? I've got to be honest and say I really don't know, but always figured the thicker wire drew no current at all with the ignition off, being the dc output, it should be going thru the diodes. Possibly way off here, but could this measurement somehow be indicating the current flow elsewhere, like the clock? Not sure where you are measuring it between.
