Could flasher be problem ?
90 softail flstc. Lost left front blinker and running light . Been searching forum for couple of days and can't seem to pinpoint problem. I changed bulb still nothing. Wondering if flasher gives pwr to running light and blinker. I have Vom and test light but haven't had time to check it out yet . Left taillight stays on but does not flash with blinker on. Right side no problem front or back. Wondering if socket could be bad and if so will I have to buy whole light. Any help would be appreciated this is driving me crazy trying to figure it out!

I did check left front running and blinker socket I do have voltage . Also put in known good bulb and still does not light. I checked wires and can't find anything broken or cut. Can the light socket be bad even though one dot on socket shows voltage?

I have see older bikes like yours have the round plastic disk that the two contacts are separated by crack and let the two springs get together behind it or go to ground. Usually takes out a fuse if it gets to the ground but I bet if the run and signal wires get together, it will not flash but you would think it would burn. I guess your one hot lead is run light. If that does not come on, you either still have a new bad bulb or no ground on the outer case were the pins of the light catch. Remember all bulbs are not created equal, and an auto bulb will be short lived when you do figure out what is wrong.

It could be under the vibration and such that they receive, may want to replace or rebuild socket. So many versions, it's hard to call that over the internet. Most have the lead button on top that you see that the lead dot of the bulb contacts. Under the disk, the spring is preloaded by the wire and keeps it all tight and away from going to ground or getting into other spring. Of course the outer shell is ground for both run and signal. Is your disk plastic or is it fiber (fiber seems to hold up) But to answer you question, yes

Thanks ripsaw. The plastic disk had turned and not making contact with bulb. I now have running light but still no left blinker. Was going to try new blinker relay but can't figure out how to get odometer **** off on my 90 softail! Not even sure if blinker relay is under there but was going to check and replace relay to see if I get a left blinker . At least making some progress anyway.
