My WC with a 12 volt generator and resister on the coil was set up with a 12 volt battery and the negative terminal is to ground. Is ths correct? Thanks

Negative ground is the automotive standard on 12 volt systems today. Some early 12 volt systems on tractors used a positive ground, but most 12 volt conversions use negative ground. It really doesn't matter, unless you are using an alternator - this requires negative ground. Many electronic ignition conversions require negative ground too. Look closely at your ignition coil - the + should be tied to the ignition source. Either keep the resistor or replace the coil with a 12 volt coil. Either way is acceptable.

original the tractor was 6 volt positive ground. many old tractors have been converted to 12 volt, usually positive ground. just need the dropping resistor on the coil as you say. starter will be o.k., mag dont care.
