2010 gas starting problems

[Anonymous-0]

I have a 1963 gas 2010 that will only stay running if I keep the key cranked on. As soon as I let off the key it dies. I was wondering if anyone had any ideas whats wrong. Thanks Bill

Well, I'm no 2010 expert, but most 12-volt gas tractors use some sort of a resistor between the key switch and the coil, to cut the voltage to the coil down to around 6 volts to keep the points from burning. The resistor is bypassed when the key is in the start position to provide full battery voltage to the coil for easy starting. When the resistor burns out, the symptoms are exactly what you've got happening.

Or the run wire goes open at any of its joints, especially the ignition switch.

I had that problem on my early 4020 gas. It had been rewired with a scotch tap that was the open problem. Mine has a resistor next to the coil so the original resistor that was either in the wiring or a part of the ignition switch had been wired around.

For a few days doing hay, I hot wired my 4020 with a clip lead from the battery post on the starter to the resistor running over the top of the hood. Proved the wiring was the problem and got the work done.
