Yes, the original shuttle switch is functional, just as it came from the factory.

I'm gonna upload some pictures tomorrow and read the other conversation where you post the codes colors and purchase the devices tomorrow as well.I did try the toggle switch today but without solid ground and felt very week engaging.

After reading a bunch of other posts, this is most likely the issue I've got with reverse. I'm reading about 12 ohm for both solenoids, but still seems to be ok.

What were the specs on the PWM controller you selected? I'd like to get one to get back up and running and then work on tweaking it to make it run a little better later.

Thanks for the work on this, hopefully it helps more of us keep these old machines running!

Just thought of this, has anyone identified the connectors needed to plug directly in without hacking up the controller? Once I get one done I’d like to share the schematic and parts list so someone in the future can build one (or make a spare for the shelf).

That's already been done, here:
