It is the generator Clive,:cry: tried it all out this morning ,fording caps checked etc and still the same. Looking in through the mesh grill on the rear at high revs it looked to be turning quite slowly and by pushing a small screwdriver through against the nut I was able to stop the genny turning easily so something must have gone amiss internally:-(.I,ll take it off in the next few days and have a look inside,i,ve got nothing to lose.In the mean time I,ll look for a replacement,may put a single speed one on depending on what I can find.There,s no extra radio batteries to worry about charging.
I,ll report back in when I find out what ailed it
