maybe it is you blinking every time they come on :laugh: :laugh:
na, its an earth issue for sure, keep it simple.
unplug all the indicators. turn the switch on and plug them in one at a time. if it doesnt work still unplug again and try another one. if it starts working, its gotta be in one of the indicator stalks (water or something) if it still doesnt work, check the wiring to see if its shorting on the frame somewhere, specially behind the headlight, (turn the bars with indicators on and see if it makes any difference. then id find the flasher can and replace it.
it will be something simple. like everyone else has said, i just explained it a bit simpler for you, coz i know how super intelligent you are big fella :laugh: :laugh:
