I'm helping a neighbor refurb a SC. He purchased an electronic distributor and neither of us have ever hooked one up. You would think that for $425 there would have been at least a badly photocopied 'how-to' sheet with it--but not.
Any one know FOR SURE where the red lead goes and where the black lead goes? I don't want to have to buy him a $125 pickup unit!

Standard color code for DC circuits is Red is positive and Black is negative. What brand is it?

BD, I'll be in his tractor shed tomorrow and check the brand. Thanks.

The make decal was behind the unit, so could see just the first word--"P". The fellow went with conventional wisdom and connected the wires red to switched and black to "-" on the coil---worked fine.
BTW, the alternator--new one wire--charged full to the + peg while I saw the engine run and had a considerable temp rise. Anyone know what a reasonable temp rise should be under full charge conditions?

Off the top of my head. The alternator should be at or close to engine temperature. Due to heat off the radiator and engine block. Depending on mounting location.

The kast one I had that got really really hot and pegged the meter had a bad regulator in it. had to swap it out after I had just put it on. how low is your batt? If it is fully charged then you may want to check further.

I agree, the alternator should not have a rapid temperature rise. Something is wrong. Put a voltmeter on the output and see what it is. It won't last long this way.

Something is not right if it's putting out more than 14 1/2 volts.
Also, I paid $95 for each electonic ignition on my 140's. The price you quoted is unbelievable. Bought mine from the good folks at YT. Also check out a flame thrower coil. It will allow you to gap your plugs at 0.045 instead of 0.025. My tractors run much better since these upgrades.

I bet he got an entire rebuilt distributor, not just the electronic ignition for that price. These are the best prices I have found on the electronic ignitions:
