Dummy voltage regulator question

[T.Jack]

Hello all,
I am in the process of rewiring my Series 1 with an new (but older version of) Rebel harness. I've read where some people are putting a 50amp fuse on the main battery wire (as I recall reading). I recently saw someones car that had the fuse built into this dummy voltage regulator. I was curious if anyone else had any experience with them. I should say, I am converting the car to an alternator. It's pricy, but I know I can buy a similar fuse thats like a circuit breaker and just trips if overloaded. Just curious what you guys thought…

Thank you in advance!!

Todd

I suspect that you are referring to a 350 amp fuse in the battery cable. "... a 50amp fuse on the main battery wire ..." would almost certainly blow when the starter motor was engaged. To provide optimal protection, a fuse in the battery cable should be located as close as possible to the battery terminal; locating it in the engine compartment provides no protection against shorts to ground between the battery and the engine compartment.

The dummy regulator assumes that you will still power the vehicle from its original flow path through the regulator.

The purpose of the fuse/breaker in the dummy regulator is to provide protection between the battery and the A and A1 terminals which are the lights and the original fuse panel. It would be in series with the other fuses in the fuse panel so it has to be higher blow current than the others (2 for a stock panel).
Its not a bad idea but not explicitly needed though.

Thank you both for replying. I’m new to wiring (as I’m sure you’ve gathered). And thank you RootsRacer for explaining wiring/purpose of the dummy regulator

350A fuse in line with the battery. PLACED NEAR THE BATTERY

About 50A (YMMV) fuse in the wire that connects from the always hot side of the starter solenoid and goes to the ignition switch. This is the power for the entire car except for the starter. This fuse should be near the starter solenoid.

With those 2 fuses in place you should never have an electrical fire.
