I'm doing write up on replacing/test stator and voltage regulator which I'll post when I get home

Will test the red wire coming out of the diode this evening and see what it does. Hopefully there is power on the red wire, and my relay is shot! lol. I've never wanted there to be a problem this bad before
! Just want to find out what it is exactly and fix it! I'm no electrician
if there is no power on the red wire can we assume its either a bad diode or a faulty stator (this sounds bad hope it's not that haha).
was I correct on checking running voltage by putting the positive side of the tester on the positive side of the battery and the negative part of the tester on the negative side of the battery? and checking that reading?

1) Ground the negative leg of your voltmeter.

3) With the positive leg of the voltmeter, touch the naked metal dots on the top of the fuse #5 (headlight / 10 A / gray wire)
4) If volts' reading there (value does not matter), follow that grey wire up to the headlight relay. That relay has our gray wire, one blue/yellow, one yellow/red and one red. We will need to measure the voltage at the yellow/red and at the blue/yellow.
5) Start the engine.
6) The yellow/red and the gray wires should have measurable voltage with the engine rotating.

I kind of did step #4 last night. At the blue and yellow I got a 0 reading with the bike running.
Will do everything you mentioned this evening once I get a hold of my tester.
Thanks again guys. I'm about ready to take this guy to the shop! But I like learning even though it is kind of stressful
