Hubie,
             It seems like a crook armature to me, check brushes are OK though.
Measure field resistance between "F" terminal and earth. Should be around 3 ohms.
The armature is not so easy to test.
Some use a "growler". I "drop test" them. Both methods need the equipment to do the test.

Which kind of generator is it?  Will need to order a new armature and brushes for it.  Doesn't look like it will be cheap either!  I am considering a 12v conversion too, apparently you just have to change the wiring setup and have the proper regulator and then it's just globes.  I have the vreg II which you can just cut the green wire to change it to 12 volt.  And a battery of course!

Cheers,

I just rebuilt my dynamo with one of these http://www.hawkerelectrical.co.uk/items/17-1_13-lucas-e3l-ac-dynamo-rebuild-kit.htm  All fitted right and works a treat. I use a similar reg a dvr2 for 12 volt.
cheers.

Dave,
           Check out Empire Spares in the UK for an armature.
They have them listed at something like A$58.00.
All of their parts are a steal!

Thanks Trev,

I'll take a look at it.  I have been recommended by a large number of people here to go to COD rewinds in Chiltern, Vic, I have it out now which was very easy (If only My Royal Enfield twin was as easy to pull things apart!).  All of my classic bike contacts reccomend him.
Time for a descision.

Have you checked the brushes yet?

Hi all,

The problem has been diagnosed as a failed armature.  I have ordered one through empire spares so thanks to all for the help and suggestion.  Have also ordered a 24 tooth engine sprocket too.

Cheers,

Hubie

Hubie,
            If you fit a 24 tooth engine sprocket and you have the standard 19 tooth gearbox and 42 tooth rear sprocket, you will seriously over gear your bike with a final ratio of 3.76:1 compared to the standard 4.53:1.

With those sprockets you will get 60 mph at about 3000 rpm, so could do 140 mph if the motor will pull it !!!

Hi guys,

It will be an interesting experiment.  I'm led to believe the RGS had a 24 tooth engine sprocket but I am not sure of the size on the box or the rear wheel.

Hubie,
             The RGS has 23 engine, 43 clutch, 19 gearbox and 46 rear which gives the same overall ratio as other A10s.
I don't know that the RGS ever used a 24 sprocket but a 22 was used, probably to help starting off with the close ratio box.

I had a 21 tooth sprocket on my RE bullet up from a 17 on the gearbox and it worked a treat.  I'll have to see how it goes.  Sounds like I might have to lengthen the primary chain too.

You will definitely have to lengthen the primary chain.

Chain has been lengthened, now just waiting for the dynamo to come back from the sparky.  Can't wait to get her back on the road!

Hi all,

I've re installed the generator and polarized it.  Can only get .2 volts out of it.  Getting frustrated.  Hooked up the test light as described in another post and no light at all (and yes, I've tested the light!).

Cheers,

Hubie.
