I'm new here..my name is Kelly and am owner of a 1971 international cub tractor...2 yes ago pretty much went thru entire tractor replaced clutch..carb...seals...bearings...gaskets and added headlites along with painting the tractor... I went thru everything except the motor since it runs perfect with excellent compression. My problem is I had a wire contact the exhaust that I did not notice until too late...after that I was just hot wiring tractor to use it which now I want to make a new wiring harness and am unable to find a wiring diagram for a 3 wire alternator using ballast resistor in a 12 volt conversion...at present it has amp meter but I am wanting to put in voltmeter in near future...any help would be greatly appreciated......thanx
