To add more, I have checked the charge over the battery terminals, when the bike is running, it is around 15 volts.
Can you give me a little more info on the STATOR? What is it, where is it on the bike?Sounds like the stator is on the way out.
Check the AC voltage on each wire and that none are grounded.
The stator is the coil of the alternator. It's inside the left engine cover.Can you give me a little more info on the STATOR? What is it, where is it on the bike?
Stators and regulators die with monotonous regularity on Honda sportsbikesCheers for this Larry. Do the stators regularly go on 929s?
If the voltage is inconsistent coming off the stator, or if the stator has earthed, will it most likely need replacing?
And a silly question, but inside the left engine cover it is dry right, no oil?
That is DC voltage that has been rectified from AC by the rectifier.I checked the AC voltage across the positive and negative terminals this evening. I do not know if this gives an accuracte reading of the voltage the bikes system is producing or not. I did not touch the battery, just the leads on and off the battery, but the battery was connected of course.
Anyway, at idle it was about 15.2 volts and at 8000rpm it was about 15.4v.
I am not sure if this is any sort of acurate reading. Any thoughts?
I think I will take it off to the shop tomorrow for them to have a look at. They will probably have to replace the ststor and RR with a used set of a scrapped bike as I'll have to order a new one from overseas.

The voltage coming from the stator before it reaches the rectifier is AC and should be somewhere around 50-70VAC from memory.
Your numbers are fine so it may not be breaking down until it's under load. If you attach a voltmeter to the battery terminals and mount it near the dash you can check it under load when you're riding over 7000RPM. If it doesn't drop below14.5V then it's probably not a charging fault.
Are the battery leads clean and tight?
run the bike and let it get nice and hot and continue checking. you may get the voltage drops once everything gets nice and hot.
Thanks for this feedback. I have been thinking that the voltage was a little high and figuired the stator was producing charge and the RR not doing what it should be doing. I will have the shop replace the regulator and will keep doing the trial and error thing.the pc3 doesn't directly connect to the battery, so it probably wouldn't cause a draining issue. If it was faulty it probably would just cause the bike run really poorly or shut it off all together.
16.5 is getting a little high. it's the RR that controls the voltage. A faulty RR will either cause no voltage to go through, or not regulate the voltage properly anymore. It looks like it may not be regulating it anymore.
there is a way to test the RR, but as the saying goes; you can check to see if the RR is bad, but there's no way to test it to make sure that it's good.
you will have to do some searching on this board for the link to a website that shows you how to test the RR.
personally speaking, it sounds like the stator is working fine for now.
what might be a cheaper alternative would be to get a voltage meter and connect it to your battery terminals and mount it to your bike somewhere up in the cluster. that way you will be able to monitor the situation in real time and know exactly when the issue occurs. 30 bucks for a digital meter vs 100 + for a regulator.
maybe something like this.

if you plan on keeping the bike for a while it might be a good investment for future use.Cheers, thanks for the idea. If the problem continues I will try this.
