After an extensive tune up, my 1952 8n ran about five minutes and stopped dead, like a switch was thrown, not like a fuel issue. The battery was new and well charged. My first thought was the ignition switch. I jumped the switch and it started right up.
Disclosure: My thumb starter switch was disconnected when I bought the tractor almost 14 years ago. It works off a "turn to start" keyed ignition switch. I replaced the solenoid (because I had one on hand, and also the ignition switch.
It still would not work unless I jumped the ignition. With the key turned to ON, I could touch the end terminal of the switch with one end of the jumper, and touch the metal housing of the switch with the other end of the jumper and it would fire right up every time. But it would never start just by turning the key. I thought maybe the new switch was bad so I put on an older one I had laying around. It did not work at all. I put the new one back on but now it would not start even when I jumped it.
But now... it will start by jumping the solenoid! I hate electrical issues! My buddy, also an 8n owner, who can fix EVERYthing, couldn't figure it out. Using his volt meter, everything seems to be drawing current as it should. I'm going to order a new solenoid and hope that will fix it.
It's a 12 volt system without the thumb starter. It has the turn to start, four position ignition: ACC, Off, ON, Start. Just as it's always had. So, exactly what solenoid do I need? I've read comments on the 12v solenoid saying it didn't work because it was a 12 + signal, instead of a 12 - signal. I'm not sure what that means. I can use your guidance. And yes, I know it should have the thumb starter reconnected, but it doesn't for now, and I need to get it running.
Thank you!
