low voltage on idle

[Oliverstrother]

Update dudes (and any dudettes)

13.3v after a few minutes, is up from 13.0 previously.

Yep stator was checked for continuity to ground. Its all good there.

Charged the battery over night, removed one of headlights, starting voltage was 13.3v. Started the bike up, warmed for a minute then held it at 5k rpm. Voltage across battery is up to 14.3v. (finally).

I checked the manual, and it does state only do a charging voltage check across the battery should only be done a fully charged battery. And the results I"m getting are now as expected.

I"m no longer worried about charging issues, I'll be replacing one of the headlights with an LED. Should be too harsh for it.

Thanks for all the help dudes, certainly has been an education.

Pretty much done with electrics for a while now, on to solving the weird knocking noise I get on start up from the cylinder head.

Ollie.

Just out of curiosity, where did you get the new stator? brand?

If you take out a headlamp bulb and the battery voltage goes up a volt then you have a stator issue.you may think you don't care because you are going to run LEDs but it is telling me the stator was not changed and the stator is on the slippery slope to failure.

"...... the stator is on the slippery slope to failure"

I like fancy electrical terms! But yeah, he's holding out on us!

 

[Oliverstrother]

the stator is new, has very low resistance wire to wire and zero continuity to ground. Fitted without any crimps or wire traps.

It came from a company called electrosport.

here it is:

I can put the headlight back in and check the charging voltage (I've not tried). Will do once the valve shims arrive.

Holding out?

A properly operating charging system can handle a standard 55W (5 amp) headlamp load with margin. If the voltage goes up by removing a 55W load then something is up.

The goop covered ES stators! potential crime scene !
So,zero continuity to ground- ohm test ? not enough. Did you check for voltage to ground during the 60 to 80 volts AC test (there should be none) ?

I may have failed to mention it has two 55w headlights right now. I've only removed one of them.

Can check continuity to ground when running (when the head is back together)

minor detail.
