Wilson Posted July 16, 2010 Report Share Posted July 16, 2010 As the title states, I want to know if you can change - say a 40 amp factory fuse to a 30 amp. After I did this swap twice, it'd make me a little bigger fish in a smaller pond. It's a temporary set up, but I want to to go get my feet wet.

Wilson Posted July 18, 2010 Author Report Share Posted July 18, 2010 Thanks for the info Chode, but I've been crunching numbers already. The thing I really need to know is, will the judges frown on me using a smaller than reccomended fuse size? I am wanting to change from my gear's reccomended 80 amps down to 60 amps. I'd be in the low 900's with my 4-10's. The stock pair of 40 amp fuses puts me into the much bigger 1001-2000 class, which would probably put me way out of my element. New build coming soon.

BenH Posted September 23, 2010 Report Share Posted September 23, 2010 Will they frown on you for running small fuses? No. How do you think some of us are getting big #'s in a low class?

Dude i have seen that s10 round town.. Where bouts you stay at? AS Far as switching fuses it shouldnt be a problem. A guy at the last show switched out 2 40 amps fuses for 2 10s to get into a lower class Quote Link to comment Share on other sites More sharing options...
Wilson Posted September 23, 2010 Author Report Share Posted September 23, 2010 Long way past this point, now. It was useful knowledge for me in the past; as it will be useful for someone else in the future, I'd say. Imagine how I felt reading the Meca rules, with my system either bought or sort of in my mind, and thinking I'd be in some mega-class with my little set up!
