8n won't stay running

Wesley B · Nov 11, 2010

My 8N will only stay running if I hold down the start switch. As soon as I release it, the tractor stalls.

Sounds like it's electrical. See if you have volts/amps at the coil with the key switch on, starter button NOT depressed.

You rewired it wrong. Probably something simple that you overlooked is all.
Go over to the Ford N board. Ask your N questions there. Lot of good knowledgeable fellows there will have you back up an running in no time.

1. Has this tractor been converted to 12 volt system?
If so you have, the run lead and start lead to the start solenoid have been switched and when you release the starter the electricity to the distributor is actually turned off. You can check this by temporarily running a wire directly from the positive of the battery to the switch side of the coil and then try starting it. Good Luck LarryT

Ballast resistor.

Resistor gets my Vote ... Put a petronix (they can aggravate a fella) coil on DC CASEand hooked it thru Resistor... if the battry was HOT it would start instantly ,,, weak Battry I could Pull it to Your house and it would never fire a lick ,,Disconnected Resistor and run Hot off SwitchAnd Now I have a D CASE that will probably start instantly if it was parked in a pond all winter ....

The ballast resistor could very well be the problem. But the 6 volt didn't have a start circuit on the solenoid.

Wesley.......the 3-terminal starter mounted solenoid needs to be mounted so the little middle terminal is facing the engine where it is hard to gitt too. ONLY the heavy copper buss-barr is between the starter motor stud and the solenoid. NO EXTRA WIRES!!! The HEAVY BATTERY cable is connected to the other BIG STUD of the solenoid with yer IGNITION SWITCH wire to the ampmeter.

Make certain yer solenoid wiring is as described, and guess what??? Yer tractor will keep running as long as the weaksister ignition switch is ON.

And yer problem has 'nuttin' to do with the "infamous ballast resistor". Ballast resistors are like litebulbs, they either work or they don't. Since you can gitt the engine to run, guess what??? The ballast resistor is NOT yer problem. .......respectfully, Dell yer self-appointed sparkie-meister

I've read all the comments about the ballast resistor...and if I'm not mistaken, ignition systems on 6V tractors don't HAVE a ballast resistor. The ballast resistor, as I was always taught, was installed in the wire leading to the coil so that what was essentially a 6V coil could be run on a tractor with a 12V electrical system.

So unless the tractor has been converted to 12V...I don't think you're gonna find a ballast resistor feeding into the coil.

Spot on. I had a wire on the buss-bar side. Can"t thank you enough.
