1972 Honda CB750 K2 - Blowing my fuse
« on: Aug 15, 2017, 23:17:02 »
I replaced the old harness and fuse box with new ones but I'm still blowing my 15a main fuse. It mainly occurs when I'm kickstarting the bike and intermittently when i turn the kill switch from off to on position after I turn the key. I checked all my connections and grounds, all seem to be in good order. I feel like something is drawing too much power when I kickstart the bike, the coils perhaps?

Probably not drawing too much power, but there might be a pinch in a wire somewhere that's eaten through the insulation. Check all of your black and black/white wires to make sure they're all in good shape and there isn't any metal poking out from behind insulation.

I've double checked all my wires and no signs of pinches or any bare wire sticking out. I can't figure out another way to diagnose the situation. My thoughts were leading to the charging system, perhaps just change out the regulator and rectifier for a dual solid state rectifier/regulator.
