Best bet is to download the fault finding chart from here and follow it step by step.

Hello

regulator, is not doing its job again charging the battery at 17V

thanks for all the help folks

Do not run the bike if your meter shows 17V !
You will end up damaging something else, as it sounds like the rectifier part that turns the ac into dc is not working, so the peak voltage will be even higher. Peak current will be proportional to peak voltage, so beware !
Also, if your regulator is faulty, you shouldnt run the bike with the battery disconnected for the same reason.
Set your meter to ac to check this. There should be no ac with a battery connected.
Putting 17V onto a battery could damage it and/or the wiring beyond repair.

Hello phil_h

Thanks for that, I needed to run the bike to get the readings,
but will not be using it until I can get a new regulator.

not too sure how I would do this though "if your regulator is faulty. you shouldn't run the bike with the battery disconnected for the same reason"

If the battery is diconnected I have no power!!

Sorry mate - I meant do not _rev_ the bike. Any voltage over about 15 is a sign of a fault.
Check you have a damn good earth at your regulator btw, as that could give false readings when you have current flowing - any resistance will give a volt drop !

Hello phil_h

The regulator that has failed is a Electrex RR51, this has never been
earthed to my knowlege over the passed 3yrs, saying that my old Duc regulator had an earth.

attaching an earth now, are you saying would give different readings?
