- Cummins 480 CE
Cummins manual indicates that there should be two power wires for each ECM on 480CE engines. Each wire is to have a 10 amp fuse/breaker.
Have looked and I can not find these two fuses/breakers anywhere. Also checked the Owner's manual and I can not find any mention of where fuses/breakers might be located.
I did find the source of power which is an unswitched breaker in the engine room electrical box. Unswitched breaker has a single wire leaving it. Somewhere after it exits the engine room electrical panel, it must split out into two wires each with a 10 amp fuses/breakers and going to ECM. Bottom line, i have found the source power wire and the place where two wires go into ECM, but not fuses or breakers in between.
Anyone know where the fuses/breakers might be located?
Thanks,
Mike
