Connecting Bar-End Blinkers

Post by schrader7032 »

Charlie -

There's a bulletin located here...maybe this will help...

In looking at my Clymer's diagram, there's no mention of black or white wires for the turn signals. A single wire blue-black goes out to the right signal; another single wire blue-red goes to the left signal. The ground for the circuit is out past the light. The power flows through the single wire, through the bulb, and then to ground.

These same colors go back to the handlebar switch for left and right. There's a small black wire in the headlight housing which attaches to the neutral light. Another black wire attaches to the "HO" terminal on the circuit board...this appears to be power for the horn. I see a white wire going from the light/dimmer switch to the headlight bulb in the housing. There may be other black/white wires that attach to the circuit board but the diagram isn't that specific. You should find a color coded diagram of the wiring and trace everything out.

Connecting Bar-End Blinkers

Post by VBMWMO »

The bar-end blinkers don't work on an R69S I bought recently, and there are two disconnected wires inside the headlamp housing (one black, one white). I believe the wiring is all original. I'd like to make sure the blinkers are connected properly before troubleshooting the wiring and the bulbs (not in that order, of course!), but have no idea where the wires should be connected. Any help here?
