  • Here's a new one
  • Here's one for you. I have an 841 gas job that fires up fine and then after a couple minutes quits running. The dash indicator light goes out and it act as if it has no powerever though lights still work. If I let it sit for a few minutes then turn the headligths on and of the dash light comes back on and I can restart the tractor. Any ideas gents?

  • First guess is a bad ignition switch, or bad connection to the switch or to the battery in the line to the switch. Next guess would be bad coil but that would not explain the light going out. Have you changed or added anything recently?
    If you bypass the switch with a jumper wire you will find out if that is it. Good luck.

  • Glad you found a relatively easy fix.
    Classic sign of bad switch is cutting off after a few minutes.

  • You kind of answered your own question, "...no power unless I move the light switch on and off...". To me that would indicate there is something mucked up in the wiring setup. Is it 6V or a 12V switchover job? If you have spark, then the next step is to first verify that the battery is good -a starter shop can bench test. Disconnect the lights altogether from the circuit, especially if as Tony asked, they are wired incorrectly to begin with. Verify wiring is all correct. Check for spark, then report back here. Note that lighting kits were always dealer optional accessories until the 800 Models, then only headlights were included on a new tractor. Here is what the OEM FORD 600/800 Series Electrical System was:

  • Hi Roger,

    Is the power supply to the ignition run through the light switch for any reason? OEM or barnyard modified?

    Bypass the headlight switch and ignition switch. See what happens. If that solves the problem isolate each individually and test.

    Battery condition? Good grounds? No white and green fur coats on the terminals?Battery in good shape not just surface charged to get it started and fingers crossed hoping the gen/alt will bring it up?

  • See tip # 13. Check for fuel and spark as soon as it stops running, not 5 minutes later.

    Post back w/ results.

  • It's electrical, not fuel. No power to ignition until I work the light switch on and off.

  • Check the battery cables and ground. Bypass the ignition switch. Check alternator.
