Combines Concave Door light on l3 not working

System works on ground activation. Ground the wire going to the cab harness. light should go out. If not look in op man for wiring harness and start traceing back til you can ground that wire and put the light out. Then either find bad disconnect or broke wire and bypass or repair. Remember wire has to be grounded to put the light out.

I would do like tbran said and take the wire that runs down the side of the feeder house and goes to the first switch if you have two switches, take it off of the swicth and ground it out and see if the light goes out. You should have both switchs hooked up identically, one wire from the cab to the first switch and a wire from that same point on the first switch running to the second switch. Then the side or middle contact of both switches should run to ground. If I'm not mistaken the switches have three screws to hook wires too, you will want to use one side and the middle, not opposite sides. I know that is a lot to take in but if it's screwed up you can't be sure you have it right without a schematic. Curt

Thanks Guys, I found the problem it was a wire that was rubbed trough and it was grounding before it even got to the switch and the little do flicker on the micro-switch needed some tweeking (bending) to make the switch push in far enough to make it ground and complete the circuit. Sure like the l3 it will run the assoff of an 7721 and keep right up along side our neighbors 9600JD -30ft head compared to 24ft on the l3 but you have to take in account the HP difference between the 9600 JD and the l3 at 158HP they sure can eat the grain for the size of machine they are. Thanks again Guys.
