Ferguson 30

I need to know how to make a Ferguson 30 tractor from a positive ground to a negative ground?

Trying to convert the tractor over to a negative ground with alternator?

Well, you're on the right tract - the alternator modification is the first step - then you'll need to replace the starter and possibly reverse the wiring on the ignition/coil circuit. All of the lighting will be fine but any guages may want to read backwards and will also need attention.
