I never had a fuse blown by my BB but I seemed to have a lack of consistent power when using the toad DC plug. After I sent BB back to have it checked out with no issues found, they sent me the dedicated fuse line plug and I have not had an issue since. However, some time after that I also had to replace my toad battery and I think that also was contributing to the power issue. Although I have gone back and forth before I bought the BB and after as to another braking mechanism, I have nothing but good things to speak to and the techs are very deliberate and friendly when I have called about concerns.
