Paul, I have a close friend who is a retired electrical engineer
If you don't get an adequate response let me know. I'm willing to ask my

The two fuses on a Bugeye are British 35A, but not everything is fused.  One=
 is for the horn.  The other fuses the turn signals, brake lights, heater fa=
n, wiper motor, and the fuel gauge.   The headlights, parking lights, and ig=
nition system are not fused.

So I would try an American spec 30A fuse or breaker.  But that's just me.  :=

Hello Paul,

There's something about the ratings of those old British fuses that's odd. They are IIRC slow blow so not rated as we would normally think them. 

I know BugEyeGuy sells a dummy regulator )for use with a GENERNATOR with a 50A fuse link. I have one. .. On the other hand fuses are to protect the wires, not the devices that utilize the power. So what is the size (and thus the amperage rating of the wiring? I think that largest other than the starter is 14, (15A  capacity in house wiring) but even if it's 12 that's still only 20A. .. On the other hand the starter is wired with #4. That's 100A house wiring and a typical starter in an MGB (from my quick research) is over 250A.

All that taken into account, I think BugEyeGuy has it correct and the 50A fuse link has never cause me any problem.

(here's where I mention that I put my STEBEL horn on it's own fuse as it draws 18A.   125db IIRC.
