Need control help on cafe project cb750 dohc

I have an 81 cb750 dohc that I have replaced the left controls with the choke controls built into the switch off a 97 cb750 nighthawk. I had to repin the switch to work with my older harness but now when I use the switch everything works correctly but after say 5-7 times of testing functions the fuse blows in the fuse box? Last time I tried it fried the diode in the main harness!! So I'm at a loss of why it's going in two different directions? Could it be a low charged battery that could cause this? Or my rewire issue? What's weird is that it takes a bit before it acts up? So I'm totally scratching my head on this one. By the way it has a brand new main harness. Your help is much appreciated :)

There are guru's here that can nail it down with you, but any time you have stuff "blowing" you can bet yer ass it's a ground issue, pull the the parts you modified and look for a pinch or a hot going to ground, trace anything that got hot to see if it somehow made it to ground... also the meter is your friend, a hot wire should not have continuity to ground unless in operation like a lamp on and vise versa, a ground should not have voltage... So ground is your friend in any automotive wire issue tracing... a gator and point test light will suffice to find an issue also :eek:

Good luck hunting ;D
