f you follow the manual for testing the regulator - which it says to check first if not charging fully - first you test to see if its grounded - yes it was, then you check with bike turned on that no current is coming through either pin - which would be called bleeding(their term - if current is found then I am supposed to replace the regulator) - since current is supposed to go out, not in and the current coming in would block leaving only a partial charging - my question is how does this bleeding occur - what causes the regulator to do something like that when its not supposed to?

The most likely cause of that is one of the semiconductor devices in the regulator is no longer working correctly. All these components are constructed from silicon crystals which have very small and precise impurities placed into them. They are rather delicate, and it is possible for portions of the crystal to melt if excessive currents or voltages are applied to them. Once this happens they can not block current as they are supposed to.

Thanks Jim - nothing to prevent it then - and the darn thing is only a year old - ah well - no big deal replacing, lol -
