I have the Type 1 for my fan and my main. They are great. I had a situation last spring where I had a dead short in the wiring harness in the steering column. Killed my quad. If I just had fuses, I would have gone through 40+ while trying to troubleshoot. Instead, I just used the breaker and it would reset in 2 seconds after the load was removed. They work GREAT! It's because of that CB that I was able to find the problem, field fix it and resume the ride.
