Starter drain the battery dead???

To me, I can swap a starter in about 8 minutes on it. If that stops the draw, then I'm good. That was my question in the 1st post, can a starter drain the battery dead while sitting. I've not had that ever. Alternators, yes. But not a starter.
Test it first. Disconnect the larger cable from the starter first and make sure everything else is still connected. If it still has the draw disconnect the small solenoid trigger wire from the starter. If it still has a draw the starter cannot be the cause because it is completely disconnected.
When you test this, use a test light between the battery negative post and the negative cable. On this vehicle, the light should not come on at all, or at least turn off within ten seconds of connecting it with ignition turned off. I would personally use a meter instead of a test light and have it selected to the ten amp scale for measuring amperage. This vehicle will show less than 25 milliamps if everything is working correctly. The draw should not be anywhere near ten amps since it takes a few days to go dead, so the ten amp scale is fine here.
