@gazza76 sorry for the late reply, after getting the multimeter out, mine was a black earth issue, so inside the loom i had 1 wire was dead, this was the black runing from the loom to the connector block for the side stand, i also then had a Black terminal on the nutural relay at the back that was not creating a connection.
maybe it helps you, easiest way i found was mulitmeter to the frame earth point at the coil. and stick the meter in contunaty mode, should beep when you touch the prongs together. and then probe all the black earths across the loom.
Cheers
