Hey Captain, can you tell me if that is what you are calling a pot on the printed circuit board? and will it count the dish movement by itself? and if I wire it up with 2 wires as if it was a mag switch?
I will try my best Pepaw.
A potentiometer referred to as a "pot" was the way older satellite receiver use to count their position, from sat to sat, an a "pot" will NOT work with newer style receivers most of the pots took 10 turns from stop to stop, with a value of 1k to 10k. lot of company's did it this way, like Birdview, Channel Master, HTS, an so on. an where gear driven by small gears like is on you'rs. mine here had that system an those gears where broke so just remade all that you see from spare parts.
now a dimmer switch in you're home on a light also is a potentiometer, as well as a volume knob on a old radio or tv.
now my circuit board use to look just like you'rs to the T, (maybe 20 years ago) those terminal strips where all rusty an in very bad shape so remove all an started fresh. now if you're asking about those black & red things on the board they are mirco switches that I use (you'rs has same type of switch with the metal bars on them) as a east an west limit, because with that mount you can drive you're dish all the way over in to the pole an damage the dish.
an you're mount is in NICE shape, I am down in South Fl an the weather with salt air an the hot sun will cook anything here, just give it time.
now I am not joking about hitting that reed switch have seen it work several times on 1s that have been sitting around, but if its hook up wrong with voltage or lighting, nothing will help DOA.
hope I cover all what you asked for Pepaw. an by the way here is a picture of the aluminium cover that I built for it, an the cover is in 3 peices, it has 3 bolts that hold it on the mount, an 4 bolts hold the face plate on with a weather stip to seal all up.
