| SORTED! (I hope)
I carried on fiddling about and then the indicator at the other side stopped working. As the rear indicators worked fine I discounted the theory the Dash unit may be at fault as surely front and rear must be fed from the same pinout from the dash.
I trace the wiring back from the indicators to down in front of the tank and sure enough at either side there are a pair of cheapo quality "bullet" type connectors. I pulled them apart and sure enough both pairs of male and female connectors were "furred" up due to road salt. I cleaned them all up and everything works fine now!
Its a bit shoddy for a 2 month old bike to be having these kinds of faults. Whenever I clean the bike I squirt plenty of Duck Oil onto the electrical connections and metal parts to keep this kind of corrosion at bay. I will have to pay special attention to these connectors in future. |
