Hi everyone,
Yes, I realize this is and electric car forum but the tech is pretty much the same (or is it?)

Attempting to upgrade to 72V Kelly KPM motor controllers.

The throttles are/were custom from a company no longer available hence no wiring diagram. From what I understand the throttles are fine with a 72V system w/o issue. That said, these do not look like normal pots as they have a circuit board in the housing.

I took voltage measurements w/multimeter while they were hooked up to the 48v system. I've attached an image with my findings for one of the throttle controls.

Note* I'm a hobbyist and not an electronic engineer so any help would be appreciated in helping me understand what I am looking at.

Thank you!
