will a powermaster 100 amp fit without notching the bracket, and i run a 4 gauge to the alt then run a 50 amp fuse inbetween then hook up to starter senoid. just want to make it right and not fry anything
For daily driving, a 100 amp fuse would probably be the most appropriate. Fuses blow as a function of current per time. Factor in that some alternators can crank out a little more than their advertised current as well.
I would keep a spare 100 amp fuse in the glovebox. I have also used an automotive/marine circuit breaker before. The convenience of being able to reset it was nice. I was leery of having it fail after some time under the hood however. I'd have a fuseholder and fuse in the trunk if going with that route.
