In Reply to: Master shut off switch posted by Plowhand on September 29, 2019 at 17:14:09:
Plowhand, To answer your specific question, YES it "could be" put on the positive cable, a battery disconnect switch still functions on EITHER post (Well DUH) its a simple DC series circuit and opening it stops current flow regardless of which post. Although a disconnect switch works, you need to locate the pesky problem, but you already know that, an ammeter and a VOM are tools which can help locate the problem. High resistance low current drains which eventually drain the battery can be a major pain lol. NOTE a simple 6/12 Volt DC test lamp may not be enough to locate the problem. There may not be enough current to light the lamp yet enough to eventually discharge a battery...…….
If the switch is "good" regardless of which battery post its on, in the Off/Open position there should be an open circuit (approaching infinity ohms on meters) through it, so I don't see how any electrical devices like a solenoid would receive any voltage whatsoever UNLESS there's an alternate current path elsewhere BUT THATS YOUR WHOLE PROBLEM which we cant locate over the net grrrrrrrrrrrrrr
