Hi everyone - bit of late reply I'm afraid but I have fixed the problem - a new regulator-rectifier seems to have solved it.  Changing the unit took 1 minute - but taking off the bodywork and putting it all together again took me over 3 hours!!  The first thing I noticed with the new unit in place was that the headlight shone brighter than I can remember before - so the old unit may have been duff from when I got the scoot...

Thanks for the earlier replies  :)

Regards

Matt

Thanks for the replies guys!

The problem is that the original battery got low every week - so I relaced with a new battery - and it too loses it after about a week and I need to charge it off the bike. 

No matter if I take the bike out for a long ride the thing just goes on me.  Last week for example (battery fully charged) I rode to work and back - about 36 miles round trip - everything fine and good.  The next day I took the train to work, so I rode to the station (about 1.5 miles).  On pulling over to park (light on, brake light on and turn signal) the bike starts hesitating in tune with the flashing turn signal - power and then no power!  On the way home in the evening I can hardly see a thing  -  the headlight is dim and I can't reach full speed unless I turn the lights off completely!!  I checked out the battery at home and it was a little down on volts.

Am I thinking correctly here?!

I think I'll try the resistance test on the regulator-rectifier but maybe I just order a new one even just as a backup.

Thanks.

Matt

Hi - thanks for your reply! 

Well I have checked things over in more depth today.  Battery showed 12.7v before starting. Taking the met-in box out to get access, I have tested the AC volts being produced by the generator.  Measuring across the yellow and pink (if I remember the colors correctly) I got 55v-60v at fast idle (cold start choke was on) and giving some gas this figure increased nicely.

So I have at least for now eliminated the generator as being at issue.  This I think leaves just the regulator/rectifier but I have absolutely no clue as to test that!  I guess as the max. volts at the battery when running is 14.5v the regulator bit is doing it's job but maybe the rectifier is having problems when the light is turned on.  Or maybe I'm going crazy and there's nothing going on and it's just my driving habits  : ::)

I think I'll see how to test the reg./rect. unit and go from there.  Maybe a new one might be the answer...

Out of interest - would a damaged CDI cause low charging when the lights are on?  Hmmm maybe I'm thinking too much now...

Thanks!

Matt

Hi guys - first post so bear with me on this...

Problem is to do with my battery - and its charging.  I have tested it with a multimeter and get the following readings:

At rest: 12.6v
Engine on at idle: climbs up to 14.5v given a couple of minutes
Turn on headlight: drops to 12.5v
Headlight on and stoplight: further drop to 12.2v

If I apply more gas - volts stay at this level but sometimes the multimeter shows figures of 10 or 11v very briefly...

If I turn off the lights the volts increase again but only slightly and stay below 13v until a few minutes when it will get back to 14v

So the stator seems to be supplying a charge - it just seems that the lights draw too much current for the stator to supply?

I would be grateful if anyone has any ideas what to check: stator, regulator whatever, or do I need to measure amps - it's just driving me crazy that the battery goes flat every few days - as its the law to ride with lights on all the time here  ;D

Great forum by the way!

Thanks in advance

Matt
