‘66 C10 turn signal help needed

[nxtruck]

Thank you guys for the help and input!
duramax55, no, the column is still in the truck and bolted up.

I wanted to update this thread and let you all know that I got the issue fixed. It did end up being the flasher. I picked up a flasher at our local Napa store this morning and swapped them out this evening. Once the new flasher was in, I had turn signals! The aggravating thing about it all is that the flasher that was in the truck wasn’t but 3 months old and was bought from LMC. And I’m not bashing them or anyone else, either. Just because something’s new doesn’t mean it can’t be defective.
Thanks again for the help and input!
