    If you have nothing in the circuit like a radio for instance that might have a capacitor in it, the only place I can think of for a significant leak would be in the charging circuit. In an alternator it is usually leaking diodes in the Alternator. In a generator it is usually leakage in the regulator. Leave the battery hooked up and disconnect the power to the Alternator/regulator circuit. Put your multi meter in there on milliamps and see if you have current draw with the charging circuit disconnected.

    Sneaky Path

When I get time I'm going to check out the switch to see if it is bleeding some current through that switch.
    Yep, that little spark is a sure sign of a sneak path load somewhere. The M38 series with the24-volt systems are notorious for developing sneak path discharge issues.

    The easiest thing to check first was the alternator so I unhooked it and still a draw. And I mean a draw so small you have to turn out the lights and still barely see it, but enough to run down the battery over a weeks time. In the mean time, I just pull the ground cable off the battery when I'm not using it.

    Mark, see if there is a very small amount of voltage at the + on the coil. Like millivolts.

    I love that we're all working on the same stuff! Unfortunately, the car is covered in snow (no garage) and I won't be able to dig into to some of these options until it melts/start to warm up. I'll follow up when that happens + when I've tried some of this stuff.

    Thank you again to everyone who's reached out - I'm pumped to learn and get my hands dirty, I just wish I had a damn garage.
