ever fig out the issue? im, having the same exact problemJust a quick update- my new regulator rectifier arrived today and i tried it out. It didn't work. When revving the bike, my voltage didn't go up at all.
I read that the unit needed grounding to the frame so I ran a jumper to the main ground, still no increase.
Then I did a resistance check through the connector, all good.
I'm going to have to return the R/R and order another.
My new cdi arrived to try the gonzo cdi also. I have to write up a connector and plug it in, but it's crazy hot in the garage right now, so I'll try it later this week.
