Honda CL350 with minimal charging

[chewy]

So the bike will start up great, and ride great, but 10 minutes into a ride, it loses spark (thought it was vapor lock, but fuel lines are full of fuel), and just dies.

The setup:
Stock Stator
New Harness (simplified and 14 awg wires)
New Selenium rectifier
Stock Voltage Regulator

I fired it up today and watched the voltage drop for a few minutes. In another test, the voltage will drop below say 9V and then it will just die!

Here's a vid on what it does at idle with a volt meter.

Starts off with a freshly charged mini lithium ballistic battery... and the voltage drops into the low 11's within a few minutes. Blipping throttle has minimal change in charging.

Any way to check if my stator is unhappy?

Use your volt meter and:
Test the battery fully charged. Should be 12.5+
Now measure it with it idling, these bikes are parasitic below 2000 or so so it will be around 12
Rev it to 3500. It should be around 14.5-15V of its not then you need to look at your wiring.

I'll check the voltage at higher RPM, but I know the wiring is right.

Yellow/Pink to rectifier, White to headlight switch....

So if the bike idles too long, it'll drain its own battery? It died on me while riding like this though too...

While idling (in video above) it starts out at 12+ volts, and drops down to 11 after a few minutes. Slowly using more than it charges...

Wire the white one into the yellow one.
The headlight switch thing is obnoxious and changes the output when the high beam is on. Might as well have full charging all the time.

Mine is wired that way. I read that normally 2/3 of stator is used, but 100% when headlight is on. So I wired mine that way as well.

Just went out and fired it up again, I measured VAC on the output wires at the rectifier.. at idle I get 6 volts AC, and blipping it I dont get more than 7 VAC.

My stator isnt outputting enough to keep it running. Any stator improvements I can do? Is there a better one I could swap in (short of the ricks speed shop ones at DCC for 210)?

I'm not sure on the upgrades, you can probably find a stock one for under 59 bucks on eBay though

Is there any way to test the stator?

 

[SONICJK]

Use your volt meter touching the leads one to the yellow wire an one to the pink wire. You should see between 20 and 50 volts. If not bad stator

I assume Volts AC, and not while running correct?
(got 6-7 volts AC while idling....)

 

[SONICJK]

And these bikes will not run without a good battery or a capacitor. The stator alone will not run the bike.

 

[SONICJK]

Yeah AC 6-7 volts sounds shot.
I'd pull it and look at the windings for any obvious breaks.
