Anyone know if the Blitz SBC-iD boost controller has an internal fuse or if it requires one.

The manual does not mention anything about a fuse so I would think it has an internal one. However, I would still like to add a little larger one but I don't know what it calls for. Anyone know?

Thanks!

 

Mine doesn't have nor did I install a fuse for it. Why would you need it anyways?

It would be to protect the electronics. I have it connected to the 15 amp circuit from the cigarette lighter (which has been removed). If the Blitz only needs 5 amps to work and doesn't have a built in fuse, then it would get damaged before the 15 amp fuse would pop if there was an overcurrent or short, etc.

Also, I want to find out if I need to increase the fuse size on that circuit since I have other things connected to it: TechEdge (3A) and FJO Injector Driver (15A), both of which have fuses.

 

I've installed tons of Japanese electronic doo-dads on my old FC (boost controllers, turbo timers, gauges, AFC's, like crazy), and none of them have external fuses. MAYBE an internal fuse, but nothing obvious.

I've also never had problems with a component blowing out. Only problem I could even think of is wiring getting damaged and shorting to ground or accidentally shorting to ground while working on something. In those circumstances the fuse of whatever circuit they were tapped into blew and I was just fine.

Might be worth calling Blitz and seeing if they know what size circuit it should be on. Dunno if it would be in the manual for the boost controller. 15 amp would most likely do the trick - should have enough headroom for the stepper motor.
