If you split the +12 and the IGN at the input to the fuse block, you can get 50A+ maxi fuses to protect each side independently. I think the housings I used were weatherpaks and it let me put 2 fuses in one weatherproof housing with a little cover.
If you are interested, I can pull my records and see what part numbers I used.
Definitely interested. Thanks. Would be nice so see what someone else has done.
So many ways to skin this particular cat. Maxi fuses, circuit breakers, resettable circuit breakers, etc.
