1966 FLH turn signal help

[eddiepanhead]

I have an issue with my left hand turn signals. When selected, the relay activates rapidly and neither front, rear or indicator light illuminate on left side. I've tested all bulbs, used deoxit on all connections and assured all grounds are good. This has been a problem with the bike for a long time. At random times the left blinkers will work......The right side operates normally.

Before I start digging in further, does anyone have any advice on where to start or what to look for?

As always, thanks for your help.

Try doing a continuity test with the bulbs in the sockets. I would disconnect the ground and positive where they begin and check everything. I’m not familiar with the wiring but I’m assuming if both are out there’s a common problem.

Is the flasher relay two pole or three pole? Rapid clicking without lights sounds like a short causing the flasher to cycle rapidly trying to reset. Then intermittently the short is open and the signals work.
