Alternator rewiring

[swanman]

Is this an excited field alternator? In which case maye the connection to the field is dud?

Not quite sure what that means. It is listed in the serive manual as a generator as opposed to an alternator.

I did take a measurement of output right at the 3 legs if I remember correctly is was in the region of about 2-3 volts. Can't remember if I used it on ac or dc scale.

2-3 volts doesn't sound good. Might be work checking none of them are shorted to ground - that the windings are not connected to the bike frame. It shouldn't have done any damage connecting a charger to the battery with it still on the bike - same thing as jump starting.

That is a car style alt,not your usual motorcycle stator and external magnetic rotor.The main windings are very substantial,you'd need an arc welder to melt them.But the rotor is an electromagnet and is powered up by the battery,kinda like the ''fields'' Ixion mentions....there are also brushes like an old generator in there.But I still doubt you've damaged any windings,it'll be a diode for sure.

Well I have taken the whole thing to my fav bike place that is panmure motorcycles. He sorted me out last time with my GPZ 1100 unit.

I think that you guys are right it is a diode or one of those techy things. I told the guy at Panmure that so I'll see what he comes back with. And more importantly what it costs.
