Well guys I took off at noon today, packed up my tools and headed out to the farm where my 8n was sitting in a nice shady spot I had towed it to after it died. I had been mowing for a couple hours a few weeks ago when it started running rough, slowed down, died, and then wouldn't restart.
Went out with a new coil, points, condenser, rotor, dizzy cap, wires, plugs and put it all in. Looked over the old girl and saw the wiring harness was a mixed up jumble of dead end wires, splices, tape, bare wires and just didn't look right. I was checking the oil and hit a bare wire and it sparked. I figured maybe I ought to go ahead and change the whole wiring harness. Got a new wiring harness with a diode for the 2 wire alternator, an new ignition switch, and a terminal block.
So I went out today in 104 heat with a gallon of gatorade and a plan. I replaced the wiring harness and put the freshly charged battery back in. ---no sparks. What a bummer. Still had lots of sun so I pulled the secondary wire from the coil off the distributor. Cranked but no spark. I was lost, all the wires were new, plugs, coil, points... everything was new. I wasn't going to give up.
My voltmeter ran out of batteries so I was kinda stumped.
Can you guess what I did to make it work?
I took the bushing and bolt out of the side of distributor where the wire from the coil comes in. Brushed it all clean with a wire brush. Put it back together. Cranked the starter and the coil was sparking. Put the dist. back together and i had one of the#4 plug out but hooked to the wire. I cranked it to see if I'd get a spark when grounded on the manifold. I got shocked! then the tractor started right up. First crank, no choke. It ran pretty good on three cylinders. I turned it and put the plug back in. Started right up and ran better than it ever had. I only had he tractor since the spring.
So, thanks to this forum I got the info to get this fixed. I remembered reading about someone else who had the coil wire to the points giving them a problem and I think that was the problem but all the other new stuff sure helped and now I have some spare parts.

Today's Featured Article - Madison's County - by Anthony West. Philip Madison has been a good friend of mine for quite some time. He has patiently suffered my incessant chit chat on the subject of tractors for longer than I care to remember, and on many occasions he has put himself out, dropped what ever it was he was doing, to come and lend a hand cranking handles, or loading a find onto a trailer. Although he himself has never actually owned or restored a tractor, he was always enthusiastic and always around helping with other peoples projects.
