Quoted from uncivil_engineer:I have a set of these I use when troubleshooting a game. Yes, you can use alligator clips on the ends of the breaker, they don't have to be attached to an old fuse. I have a couple that have a piece of wire soldered to the terminals leading to alligator clips. Just be careful that you don't accidentally short the two terminals on the fuse together while using them.
Thanks for the answer. So, I can attach the crocodile clips to each end of the fuse holder and not use a dead fuse at all? I will have to be extra careful when I try again as the last time the whole garage tripped and I thought I had blown up my prize possession.
