Did I ever figure what caused 30amp fuse to blow? Starter?fuel Control solenoid ?wire rub theu and touching bare metal?

[@natcoziay]

Yes it was an electrical short. The wire had rubbed through on the frame of the truck.

Reefer on trailer keeps blowing fuse.
Any suggestions? Tyty

[@natcoziay]

Sorry for the long delay, but if your fuse is continuously blowing, you have a short somewhere.

Where is the main power fuse located

[@TheTinkle1]

On the mother board

[@franciscastillo8588]

you ground from the reefer unit to the trailer is bad

[@richardsonchangeux2711]

My keep burning the 30amps

[@natcoziay]

If it keeps blowing fuses, you have an electrical short. Chase the wires running under the truck until you find the short. I have another video explaining the same problem and how I fixed it. More than likely, the electrical short is going to be in the wiring harness attached to the frame of the truck. Look there first. Good luck
