1966 turn signal fix needed

[Tony S.]

I have a technical question. My right turn signal is acting up. When I turn on the right (pass side) turn signal, it doesn't flash. The light indicator on the gauge cluster, rear lamp and front lamp just stay on with no blinking. Suggestions for a fix? Thanks, Tony

Tony, This is going to sound unusual, but......

Change the flasher.

A few years ago Harry Sadlock had similar issues with his car. Read this one. Other folks reported similar oddities and they solved with flasher too.

Since all of your lamps light up on that side but don't flash, the combined current may be a tad less than the other side and the flasher can't "release" the internal contact....then repeat.

The only other thing I can think of is a poor ground or power connection with one of the bulbs or sockets. But a bad connection usually increases current due to higher resistance.

Tony, one other thing...

Make sure you have the correct flasher for a '66. Since it has only one tail lamp(per side). I think they're different than the 2 tail lamp cars.

Tony, Did you get a change to diagnose your problem? Very curious.

Hi Rich. It was just a loose wire. I re-attached it and it worked! Thanks for your help. Much appreciated!
