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

Today's Featured Article - Hydraulics - Cylinder Anatomy - by Curtis von Fange. Let’s make one more addition to our series on hydraulics. I’ve noticed a few questions in the comment section that could pertain to hydraulic cylinders so I thought we could take a short look at this real workhorse of the circuit. Cylinders are the reason for the hydraulic circuit. They take the fluid power delivered from the pump and magically change it into mechanical power. There are many types of cylinders that one might run across on a farm scenario. Each one could take a chapter in
