My k3 battery dies when using heated grips

[Big ted]

Me back again guys
Charging issues now.
Checking charge rate at apx 3000 is 12.67v
Stator volrage from the 3 yellow wires is 60 to 62v new battery and rectifier fitted but still only getting a charge rate of just under 13v
Bike runs and starts ok but if i use heated grips it wont start once ive ridden 20 mins or more.
Could this be a stator issue or the wiring from stator to rectifier.
Has anyone got wiring diagram or directions to obtain one please so i can rewire it and tick yet another box

Ted, do you get same reading earthing at battery and motor?

Good voltage from that stator but poor charging points to the reg/rec. I hope you've got small hands to take it off without removing half the bike as it's near the swingarm pivot.

I have heard of the connector rotting and causing issues. There is a full test procedure in workshop manual for the reg/rec too.
