M35A2 Lights

[klq9386]

As I drive down the road the lights (interior and exterior) and turn off. After about 30 second (sometimes less) they come back on. I didn't know where to check from a ground / wiring perspective. Any help would be greatly appreciated.

Circuit breaker inside the 3 lever light switch is cycling. It could be a momentary short to ground somewhere, too much load, or a weak circuit breaker.

And that breaker can not be manually reset. It is auto resetting

I dont know if it helps, but when it is acting up turning the switches off and back on it stays off. I dont follow where the circuit breaker is? Mind helping explain where I need to check?

Warthog, can it be replaced?

 

[Warthog]

It is inside the 3 lever switch. As far as I know it can not be replaced.

 

[klq9386]

So I would need to replace the 3 lever swtich unit as a whole?

You can find a switch at most of the surplus vendors.

Mine would do the same thing when I ran with the high beams on, weak thermal breaker ( as already mentioned )
was my problem changed out the 3 lever and all is fine

Wire the headlights tru relais, more light from them and less current tru the 3-lever switch.
