650ss charging problems

I have a 650ss which is not charging the battery. The bike is fitted with a new regulator /rectifier unit and a Pazon electronic ignition. The stator and rotor are original. I have checked the stator output and am getting 30V ac across the 2 wires from the stator.I have also checked the resistance down to ground which is infinite

Can anybody tell me if the voltage measured at the stator is correct for the regulator /rectified unit (Areg one from Paul Goff).

Also what is the best way to check the reg/rec unit and any other suggestions to check the stator would be much appreciated.

Thanks

David

If the battery is fully charged then it won't charge, leave the lights on for a bit.

As both the above answers are total rubbish I suggest they are ignored.

The testing of the alternator can be done by going to the appropriate pdf on my web site. But your test is useful although as regards an output voltage this is not very useful, better to power a lamp-as per test on web site.

Testing of the A reg I can fully test these. If you send it to me with return postage (£5) I can test it.

Can you tell me why the voltage reading is not very useful information ? Is this not an indication that the stator is working ?

Thanks

Right 'ere we go. Just about every Multimeter we would be using is designed to measure mains frequency 50c/s and the RMS of a sine wave. BUT from your bikes alternator we have a variable frequency some 60c/s to many hundreds. The wave form (form factor) I can assure you is disgusting due to the way the magnets wizz past the coils. Then there is the fact that voltage is one thing while 'power' is another. So if you test with a single beam from a headlamp bulb and it glows bright then you have 45W! and no arguments.

Modern cheap digital Multimeters also pick up ignition interference and then jump all over the place. If you have no electrical knowledge do not poses a Multimeter and even less understand how to use one, then you can still do a light bulb test and it will have a lot of meaning.

Here endeth the first lesson.

As we heard no more about this non charging fault and the reg/rect was not sent for testing we must assume that David Metcalf got to the bottom of this problem. Good.
