Turn signal beeper???? 1980 CB750K

[saltracer]

In the box of parts that I received when I bought my CB750K was a beeper that looks to be for the turn signals???? Can anyone confirm that a 1980 CB750K had a turn signal beeper as stock??? I cannot find it on any electrical parts list that I have searched.

They were stock on sohc models, but not on the dohc models like yours

1980 CB 750 Custom Turn Signal flasher.

I'm looking for the schematic of the stock turn signal flasher. Mine isn't working. I took it apart and it is serviceable, but i need the schematic to go any further. Or at the company that made these elaborate flashers. Can anyone shed some light? It's much bigger than a typical flasher that you would find in an old 60's or 70's car.
Please help. Thank you.
