Hey Murf, does it have a candohm resistor in the chassis? It sounds to me like a bad resistor and if it has a candohm that would be the first one I would sub out. If not, start checking the other resistors and see if any are high and change those first. It's also possible there is a bad ground connection. Lots of things can cause this issue.
