Thanks Max,
Wiring is all new, battery is new, rec/reg is new, I have ordered a new stator but I don't believe this is the problem. I have worked for years on Enfield charging systems so I have a rough idea how they work and this system is so much simpler, plug the rec/reg into the stator and connect the red wire from the rec/reg to battery positive, can't get any easier than that. Got me a bit stumped at the moment. If the stator is putting out 25 volts ac with the revs it is running at then it should be fine for the dc side as well
