Greetings, Idaho with 82 KZ750 and 77 KZ650

Greetings everyone,

New guy here in south west Idaho. Losing what hair I have left chasing an electrical issue in my 82 KZ750 has brought me to this fine forum. I’ve been riding for about 18 years. I think I’m up to 9 or 10 bikes since I started riding. My main ride is an 07 Victory Kingpin I bought new. Recently wanted to get into some vintage bikes to work on with the kids...now I have 4 projects in the garage 82 KZ750 (was running till my 3rd ride), 77 KZ650 (Untouched and not running), 78 Yamaha XS750 (running prior to purchase, yet another electrical issue) and a 72 Honda CL100 (total restoration needed). I have a good wife, all 4 bikes showed up over a 2 week period, no drama on her end lol. Anyway, I’m used to routine maintenance and some minor-moderate repairs. I’ve dabbled in electrical in the past but generally hate it. I much prefer fab and design. Hoping to find some answers around here!
