GS1000SN left handlebar switch not returning to middle position

[Rijko]

1979 GS1000SN, with TSCU and left handlebar switch that has the manual push down to cancel switch.

Pushing down system works, but after pushing the lever L or R it does not return to the middle position.
The manual states it should.

Does anyone see/know what makes the lever return ?

I have a feeling a spring is missing, or maybe more parts.

I was under the impression that it doesn't return to center automatically. AKA - self canceling... The later models that self canceled did auto return to center but the flasher relay self canceled the turn signal based on speed - a system that didn't work very well.

I do know that my 77 you push in on the signal switch to cancel the turn signal and it doesn't return to center by itself.

The later year, square button, hand control does NOT return to center. It's a momentary contact switch, so even if the button is off center to one side or another, there is no electrical continuity to that side. I've not messed around with the early hand control, but it may function the same way.

i sold the only bike i had with this TSCU setup ... my other GS1000 and GS1000S bikes have the simple setup.
New owner had issues with the turn signals.
Would have liked to troubleshoot further but for now he just wants the blinkers to work.

After disconnecting the speed sensor it now works fine, except for the auto cancel.
