M35A2 Headlights / Brake Lights

[Bigfoot111]

Greetings! I had to jump my Deuce last night and after I got it started, I found that the headlights would not come on and the brake lights would not activate. The BO lights work and the panel lights work. It is just the two stop lights and service lights tab on the right side of the switch that don't work. Any thoughts? Do I need to replace the switch? Kinda a newbee at Deuces. Thanks for any response!

That three way switch can be tricky, make sure you have it on the correct setting. If you have it on BO your lights won't come on.

HELP! I hadn't run by Deuce for months, then when I started it, no lights anywhere - no blinkers, no dash lights. Truck runs fine! Where do I look? Thanks!

I've attached a copy of the wiring diagram for the M35A2.

Wire #15 brings power to the switch. It gets it from wire #10 which brings up all the cab power. #10 is probably good because you had power at the start switch. Start with wire #15, pin F on the 3 way. Typically deteriorated connectors and or wires. 50+ years tends to take its toll.

The funny thing is last night I started it again, and the only light in the whole truck was the red light to let me know it was locked into 4x4 - and when I shut it off and restarted it again, the red light was gone! And now it is snowing again, so who knows when I will get to it - hope this weekend. But THANKS!
