Ironhead XLCH Crazy voltage spike

[smokey 2]

I guess I did it right, thanks.

I believe [but I do not know] that the CS gen that is polarised from the factory is the one that has the regulator attached; the other gen is not polarised from the factory.

electronic regulators really do not need polarizing.
with electro-magnetic coupling, current flow can go both ways and if not correct, the coils work in reverse which causes the regulator points to burn out and usually the shunt resistor on the back.
electronic has diode blocking and no magnetic coupling. when it is powered on, current flows only in one direction and that direction is correct to polarize the shoes.

Hey all, Doc suggested I hook up a light for the generator to help with the diagnosis.

In short, when the bike motors off but theres power the lights strong and steady.

I filmed it when running/idling though and this is what happens...

Im pretty sure the light shouldn't be on, this dosent make things any clearer for me but might mean something to someone else.

I cannot see clearly where the wires are connected. Perhaps you could give a verbal description.

the ground is wired to the 'L' terminal on the generator and the positive is connected to the same terminal on the ignition switch as my headlight.

I’m kinda out of any further ideas as nothing seems to be working. I figured all that’s left to do is post my wiring diagram in the hope that I may have overlooked something here...

Key:

HL: headlight
TL: taillight
JB: junction box (this is the channel with terminals on it that is part of the frame)
BS: brake switch
SP: spark plugs
P: points
CB: circuit breaker
B: b terminal on CE dgv5000

Failing this I’m going to take it to an auto electrician.

Hopefully I won’t have to send the gen/reg back and that’s going to be an absolute nightmare!

Question, does you switch have both an acc, and an ignition post?

Yeah there are 3 posts, battery, igntion and acc.

I can take a photo if that helps...

Some interesting observation today. Where I thought I had blown my recent taillight bulb on the ride last weekend, it turns out that it hasent actually blown (yet) but in fact its actually reacting to the voltage much like the generator light that I have just hooked up. On idle the taillight is flickering (very unstable and dim) but under load its going out completely.

Just to confirm this is whats happening with the generator light as well. Its flickering very low on idle but then goes out under load...

This to me makes me think that the generator/reg are doing their job?? I'm probably wrong.
