[AT] A-C WC battery

[Mike Sloane]

I agree with Charlie Hill's comments. Also check the ignition coil 
(unless it is a mag engine). If the job was done properly, on a negative 
ground system, the wire coming from the ignition switch should go to the 
"+" terminal on the coil. Unless the coil was changed out, there should 
be a "ballast" resistor wired between the ignition switch and the coil 
to drop the voltage. Otherwise, you will burn out the coil.

I am unaware of any standard alternators that were other than 12 volt 
negative ground, and few farmers would go to the expense of using a 
specially modified alternator.
