Yesterday, the turn signals on my R75/6 decided not to work on the left side. I removed bulbs, cleaned and located a loose ground wire on the left rear unit. Once all these were corrected, the signals began blinking slow, then fast, then slow again. Front and rear lamps are working on both sides and the erratic flashing occurs whether left or right, engine running or not (suppression issues should not be a factor). I may have missed something in the wiring, but is this symptomatic of a bad flasher relay? Before yesterday, they were working perfectly.
