Trees are a wonderful thing, they pay for bikes when the weather is good. When bikes go wrong especially when its electrical I don't bode well in the repair department, orig prob not charging so got a new rectifier (connector plug full of crap and water) and it was throwing out 14.3 to 14.6 volts (ideal), when reassembled I checked again and no more than 12.3v at well over tick over. Got another new rectifier yesterday but no different. I guess there must be a break in the loom or stat coil breakdown. Now rained off for rest of today, so bar a bit of paperwork first I will shut myself away in the shed for a while and ponder the problem with multimeter in hand. Will report back later. Thanks Barney.
Well problem sorted , and now got 14.6 volts at battery I've hard wired the rectifier in to the loom. Fixer got wind of my post earlier as was obviously in fixing mode Thanks Neil and Andy.
