Farmall 400 Rear Light

Tim Nichols · May 13, 2017

I have never seen this problem before. I installed a new rear light on my 400. It comes on in the 3rd. position of the light switch. I also installed 2 new headlights. They work like they are suppose to. Dim on the 1st. position, bright on the 2nd. position and stays bright in the 3 position. The problem is the rear light will not come on now with the switch in the 3rd. position since I put the headlight on. I switched this tractor from 6 volts to 12 volts 10 years ago and all was good.

Any ideas what might be causing this?

Thank you,

standard 400 should have a off, dim and bright switch. Rear light wire goes next to dimmer coil terminal on one side and front lights on terminals other side of dimmer coil.

(quoted from post at 12:40:11 05/14/17) standard 400 should have a off, dim and bright switch. Rear light wire goes next to dimmer coil terminal on one side and front lights on terminals other side of dimmer coil.

Thank you, I will pull the switch out and rewire.
