We recently restored a Allis WD 45, 1957. The only way tractor will run is with Negative being ground and I know it is supposed to be Positive ground. Since the motor had just been rebuilt and tight, we are using a 12 volt battery, generator is not hooked up yet. We just took a wire from the negative battery to the coil, negative side of coil to make it run. Every other way we try to connect it, tractor or points would not fire. What have we done wrong? Thanks John

Well first off how a battery is hooked up should not make any difference as to if it will or will not run. The coil will work either way but it works better if its hook up the same as the battery. I.E. if you have it + ground then the + side of the coil should go to the distributor.
Also if you ask this in the Allis forum you might get more answers.
