Hi Jerry, all good sound advice from your self and the other guys. What happened to you is a nightmare when on a run. I know just how it can spin out of control, took the wife out for a day trip her first ride when l first got the bike we where about 100 miles from home and 4 miles from our destination when we got a flat tyre in the rear. To cut a long story short, it was a new tyre could not be repaired had to spend the night in a travel lodge transport by cabi. 40 some hours later we get back home, the cat going nuts hadn't eaten for two days. So yes, road trip break downs can do your head in.
Anyway back on topic, I spent the day doing some research, btw. Your diagram was helpful prices here run from £164 down to £68 online. Don't know the exchange rate but getting from your side of the pond l can get one for $98.oo £64.00 plus shipping.
Started to pull it out today found how to run test on it and the stator.
As l was checking l came across a harness plug that had the green oxidisation on two of the pins didn't know what the plug and harness was for,...It run from left to right underneath the seat just below the tank. Back to more digging and found it to be the ignition harness. Not sure if that would have caused the glitch, anyway cleaned it up gave a shot of ACF 50 and called it a day went in for dinner. Carry on in the morning.
