I don't see any dark spots, other than the blue paint pen marks ...

If you can't get to the backside of those to test, just remove one at a time, and check for power where they plug in, that will tell you if you have power to the fuse block, if you don't, then you have probably either a mouse problem, or a chaffing/pinched/cut wire situation, but either could also blow a fuse ...

If you have a multimeter ... Set it to check continuity and test like shown holding both leads together, then between both blades/pins of the removed fuse, if you have a solid ".000 like this, your fuse is good, it could show a little resistance like .005 and still be good.

But if it shows 1.0 like this, when both leads are separate, then fuse is not good.

I checked today and all 4 slow blow fuses are good. I pulled them out and using a voltmeter they showed "0". I also used a test light and pierced all 4 wires to the fuse box and they all showed power to them. So I can scratch them off as my problem. In the morning I am going to check the five wires on the key switch for voltage. I checked them with the test light and got power to all but not sure how many volts. After that the only other to do is to start bypassing safety switches to see if one of them is the problem.
