So my old ass cb750 had all original electronics. Fine for 1973. Not so cool for 2015. I upgraded to a solid state regulator-rectifier from the old mechanical unit, then I looked at the snotty old glass fuses and they just didn't match. Pulled this off on the cheap, not by design just worked out that way. $7 EBay 4 circuit blade style fuse block and a $5 pack of insulated terminal connectors. Ridiculously easy and cheap mod for any vintage scoot. The fuse block Even has a waterproof clear cover with o ring. Has extra circuit for farkle lights or I just keep a spare 15 amp main fuse in it. Best part was I did it inside in the air conditioning.
