Guest makes a switch that has longer studs and will fit in the existing hole, that along with the 45 degree lugs, might be the ticket.
The 2 smaller red wires go to directly into the harness and are then divided up into to feed to each of the fuses at the switches on the panel. There are 9 switches and fuses. The travel distance from the battery switch to the fuse on the panel is approximately 18".
I am considering putting in an inline blade fuse on each of the red wires. The problem would be that I have absolutely no idea what size fuse would go there.
I know the answer is "depends on the length of the circuit, the size of the wire on the circuit, and the number of circuits on the panel". I do not know the distance of every single
circuit that travels from the panel to its ultimate use. I don't have the means to track them under the settees or above the head
liner to their ultimate source. Where I have been able to see it the wiring
harness is a bundle of wires as thick as my wrist.
I suppose one possibility is to start with a 10 amp fuse and turn on everything on the panel. If it blows, go to a 20 amp fuse etc. until I get over the nuisance blow level.
The red and blue wires are also about 18" and just go to each volt meter.
