hey guys, my name is kev... right, well as the title says really, the indicator tell tale light on the speedo isnt working, ive taken the speedo off and thought it would just be the bulb but the bulb is fine... so i got a multimeter and tested the conncetor and the power isnt getting there... but the bit im kinda confused with is that the wires are brown and dark green, on the wiring diagram it shows said 2 wires are coming from the indicators and therefore the 2 wires should both be positive?? but they cant be as it would need an earth? There is just the 1 bulb, not a bulb for each direction. I think all the indicator wires go to the turn switch on the handlebars so i guess i need to take that apart? If any1 has any input please post up, i`m no wiring expert Many thanks, kev
