Re: Battery draw

Ratty is correct, check to insure the switch is indeed open when off. If you're running the kill switch through the negative side & the battery is still discharging with the switch off then the battery case is dirty (allowing a path to ground) or you have a bad battery. Did it discharge when you were disconnecting the cables?
The real solution is to locate the key off drain. Unlike newer vehicles, these trucks don't have a lot of components that will cause key off drains. I would check anything aftermarket that is wired in first, second I would check the alternator/regulator. You really need an amperage meter to check for drains but a test light will work in a pinch.. I'm sure there are some youtube videos out there that do a better job explaining than I can.
