856 Custom 435 Posted May 5, 2019 Share Posted May 5, 2019 If you have juice going to the switch to the terminal that feeds the switch with current, the switch is bad. If you don't, run a hot test wire from a hot terminal somewhere. Fuse box area or the battery even. Leave all the wires connected on the switch and touch your hot wire with the terminal on the switch that is supposed to feed the switch with current and see if you have any lights. If you still don't have lights, unplug the terminals from the switch that feed the lights current that aren't working and put your hot wire to them and see what happens. If they work then, throw the fuse panel away and put a new one in. They're a B to change, but better than hacking wires and making a mess with circuit breakers. I've had a light problem on the anteater and a couple 86s and the new fuse panel fixed it even though I couldn't visually see anything wrong with it. Just trying to help you figure out what's wrong before you go out and buy a new switch and install and find out it's not the problem. Quote Link to post Share on other sites
jjohn 0 Posted May 7, 2019 Share Posted May 7, 2019 Either the switch or corroded fuse block. Check the green wire connected to that space connector. My fuse block was rusty and corroded. High resistance = fire and wiring issues... 🙄 Quote Link to post Share on other sites
Missouri Mule 1,642 Posted May 7, 2019 Share Posted May 7, 2019 I’d bet money your switch is bad or the connection is bad on the switch. I’ve had lots of trouble in that area with both of mine. Quote Link to post Share on other sites
Mike56073 232 Posted May 7, 2019 Share Posted May 7, 2019 It always amazes me when I open up our 56/66 series tractors behind the dash. Some stuff was really never engineered well in terms of wiring placement. I always thought about that when I had something hooked up to something that vibrates, like a stalk chopper.

stronger800 836 Posted May 7, 2019 Share Posted May 7, 2019 Sounds like he correctly jumpered across the switch to me, taking the Hot wire that feeds the switch and connecting it to all of the switch output leads (the wires that go to the lights). Only better way would be to leave the switch hot feed wire plugged into the switch, (he said it has power) and testing each terminal with a test light as the switch was turned through all positions. According up what he said, that should show the switch to be functioning correctly, and point to separate wiring issues out in the field and road lights. Did you check at the lights themselves s for power? Maybe you just have a bunch of blown bulbs. Quote Link to post Share on other sites
IH1066 BlackStripe 3 Posted May 8, 2019 Author Share Posted May 8, 2019 i forgot to mention when i had the flashers on in the first position the rear left field light was flashing with the flashers i checked all the wires and fuse block is ok power on both sides of fuses have not had time to mess with it yet since saturday Quote Link to post Share on other sites
Matt Kirsch 881 Posted May 8, 2019 Share Posted May 8, 2019 Bad ground(s). When lights start acting like that, the power is backfeeding through other bulbs to get to ground. This is why you'll see a pickup truck for example with one dim headlight. That headlight has no ground and the power is backfeeding through the high beam filament to get to ground. Better than mine. When Dad pulled up the deck plate to fix the range shift linkage, we found all the light grounds taped off. Quote Link to post Share on other sites
