[griffo117]

ive had this prob before with the r/rec
its currently doing 12.4 v at idle and ive checked the best i can everything even tried a new 1 and it is 11.9v so wtf
volts do increase a bit up to 13 at high revs i thought it was the stator but apparently its fine so any ideas guys the reg/rec isnt burnt out at all and the wires are perfect so HELP

Check main earths onto back of engine and frame.
Suggest you run a separate earth to the rear subframe from the battery neg terminal.
Also battery connections.
