[Spridgets] circuit breaker

[Rick Fisk]

Jack,

I was doing some simple adding in my head when I came up with the 30A number.  The unfused standard headlamps are about 4-5 amps each, the parking lamps are probably another 2-3 amps.  I know from personal experience that you can safely replace the British 35A fuses with American 15A fuses and they don't blow.

Maybe a better way to go would be to fuse the unfused circuits.

Rick

I bought a large circuit breaker a while ago but never did anything with it because I didn't know where to put it or if it was even needed with all the existing fuses.  I wonder where a high amperage short could happen that would not be handled by the fuses?  Between the alternator and battery?  Or, battery and fuse block?   I've only seen something like this on one LBC so I guess not too many people are concerned about it!  Breaker shown is a 100 A, Napa/Buss 782-3114
