I omitted most of the factory wiring used updated switches, hardware and mechanical gauges. Converted to a 10si alternator,gear reduction starter, and a group 31 12 v battery haven't had any issues since took me about 8 hours or so to get everything together. I got my tractor for a helluva deal so I didn't mind putting a little into it. Have heard horror stories about these tractors but from my experience with them they are decent tractors. The tractors are crude and could use some refinement but overall I'm happy with what I have.
