Why not try one just in case there is something with yours that can't work right with the engine running. If you buy it & it's not the problem I'll buy it from you to keep as a spare. I got mine working for the first time in years & it really is nice to have them. Sometimes even just to tell other rudders of a group a turn is comming up and I like the (maybe false) scense of safety when sitting at a light waiting to turn left I feel a bit safer from some cell phone coma induced driver not seeing me sitting there! Anyway, good luck.

Electrical stuff is all Voo Doo science to me, I understand the path it follows & the basic stuff but not what's really going on inside those wires & goofy contraptions so I start with things that are known to work togeather. What else is there? Could a short cause those symtoms?
You will need some bypass caps across the leads or it won't work.
Put a 0.33uF cap between pins 1 and 2 and put a 0.1uF cap between pins 2 and 3. You could also throw an additional electrolytic cap on the output between pins 2 and 3, something like a 4.7uF, but this may not be necessary if the LEDs aren't pulling much current.
Pin 1 is on the left side if you are looking at the front of the transistor.
See page 23 for cap connections:

My hunch is that I've got some marginal connection that that's getting current to the flasher but not enough to power up the mechanical flasher. I checked the connections with a voltmeter and they seem to be ok but voltage and current are two different things, so maybe a marginal connection somewhere. Maybe an electrical flasher won't be affected.
