Our 1940 9N has CM HALL style headlights. We just got the tractor wired up properly and we're working on the headlights. Can you show us a pic of where the ground wire is connected on the headlights? We've tested the lights and they work when we run a jumper from the base of the bulb to the frame of the tractor. Just to know where/how to connect a permanent ground wire.
