That was where we started first, the draw sucked my batteries down to 0.0 volts, to be fair they were 14 years old. The frame has a stud that the negative cable goes to, we cleaned everything up, but I suppose we can check continuity of the cables, the truck will start, just not with the key, so I have to have decent connections for that portion. It does have two ground cables going to the disconnect switch, that seemed odd, but everything was working until a couple weeks ago. We eliminated the disconnect with no change, so I don’t think that is our issue either. There are a lot of variables at this point, we figured grounds, so today we are going to start systematically checking things and making notes.
