Circuit Breakers
Does any one know how the circuit breaker in these trucks work ? There's no reset on it.. Does it reset it self or is it like a fuse once it trips it has to be replaced ?

Re: Circuit Breakers
It should reset itself. I believe it is a thermal type. It gets hot from a short and then cools and resets. Before my new harness mine tripped all the time. 
When it is cold it should have continuity or pass current. If it is open when cold it is a bad breaker.

Re: Circuit Breakers
You can still buy these brand new in both auto and manual resetting.
