May be your main fuse located under hood in fuse panel
It will be like a 30 /40 amp
Is it the battery fuse 80A?
Can be. Look at your schedule when you lift the cover you will see the print on the inside
If your unsure I will Google for you. But that fuse provides power to cab and engine compartment
40 amp green color under hood
But what your seeing is a fusible link which also provides power to cab. Check that too! Lift the plastic cap off and test with tester to make sure power is supplying cab
If there is power to both those move on to main harness that is plugged in cab. There is 2 bolts holding plug to internal fuse panel. It may be loose.
After that your ignition disperses power to everything so good luck!
