tidily hand drawn document

Hi All,

I noted there was no main fuse in the "tidily hand drawn document."

I was thinking of a main 70amp fuse or is overkill?

If you could provide a link to the document in question, please, it would make replying much easier?

Hey Gord,

this one from the

Do you mean on the main feed from the battery? 70A may be a little high but shouldn't hurt, 50A may work just as well. Because I loathe voltage drops, make sure the wire gauge is adaquate with a minimal voltage drop along it.

I do like each circuit being fused, but my preference is to fuse the main supply to the relay(s) rather than after, or a fused relay/circuit breaker, but that's me and I like to have them as close to the source as practical to protect more of the wiring against shorts.

Thanks, Gord, that lines up with my thinking.
