Wd 45 battery hook up.

Wesley.davis · Apr 30, 2018

I just picked up a 1956 Allis Chalmers wd 45. Put a new battery in it. Tryed to start it and both cables melted. I thought that if it had the alternator change over it was a 12 volt negetive ground. Please help the old man who ones this was very important to me and I would like to use it.

Define "both cables melted".

If the insulated wires on both battery cables melted you have a pretty serious shorts.

Even getting the alternator polarity wrong wouldn't cause that.

Could be a shorted starter switch, a shorted starter, or the starter dive could simply be wedged into the ring gear.

As Bob said and or a bad starter or a jammed starter drive which in turn locks up the engine and starter. Or the cables are way to small for the load

Bench tested starter. Works great. Brushes are fine. Bearing good.

Could it be that the insulation on the inside of the button solenoid be bad so it is just grounding out there?
