as magg has said, any reading to earth from the stator is a bad sign.

your voltages look a little low too and your reistance for the stator coils looks a little high.

time to get the side cover off and do an inspection of the genny itself, from the readings it sounds toasted, could be the wires have got too hot and melted shorting to earth etc.

yes your connection from the genny to the reg/rec must be re-done with solder.

probbaly have to get a new genny first.

battery also sounds really knackered too, is it old?

start with a new battery / genny and reg/rec. ensure all connections are good and keep the battery fully charged when not using for more than a week or so.

Hi all,

After a year of using this site i was re-reading some of my Topics (Time on my hands, i know!)

Though i had replied to this, am sorry that i didnt.

After fully replacing the bike with a new battery (A nice an expensive one), the stator and reg/rec, the bike worked well.

After fixing it and doing all the tests talked about, i drove the bike to Germany and back and alls been good since.

One more tip to people that dont always have the time to ride there bike would be to buy a battery optimizer,

MAKES YOUR LIFE SOOOO MUCH EASYER!!

Thanks again for the help,

Andrew.
