Super H Rear light

[DV]

I am putting a new wiring harness on my super h and am wondering if the rear light is wired in on the same terminal as the front lights? Also what does the little coil on the light switch do? Thanks

The rear light gets wired to terminal #2 on the light switch. The front lights wire are wired to terminal #3.

Properly wired rear light will burn brightly in both the D and B switch positions; the headlights burn dim in D and bright in B.

That little coil on the light switch is the dimming resistor for the front lights. Be aware it becomes quite hot when the lights are burning dim - make sure no other wiring is touching the resistor when the switchbox cover is in place!

Thank you for the info. I don,t know if I noticed the terminals being numbered. I asked the question because I never had a rear light on the tractor. I'll have check it out in the the a.m.

The resistor just dimms the front lights (no real good reason to do that, they are not deadly bright any way, but the diagrams should help. Jim
