Symptoms were turn signals coming on but not flashing, or sometimes failing to come on. The latter more often on the right. Original flasher would click once on turn sign on, and sometime buzz briefly as right side was turned off.
Ensured grey wire was on load side, no change. Tried out a known good thermostatic flasher and got no lights at all. That puzzled me, I expected slow flash or lights on no flash. Still puzzles me really.
Replaced with a heavy duty automotive flasher, pic attached, perfect function restored.

If i remember correctly the automotive flasher doesn't cost much either.
