My dad and I have constructed our complete observatory including the NexDome walls, dome, bays, etc. We installed the track and motor last night and tested things out only to discover the motor only turns the gear one direction and when pushing the the button to rotate the opposite direction nothing happens at all.
Is there some kind of polarity issue I’m missing with the power supply, or maybe some other piece if hardware or switch I need to flip? Or is this just a bad unit? I’m fairly handy and have messed with switches and gears and electronics over the years but I am certainly no expert, so I feel I could easily be missing something simple or not understanding something.
Any help is appreciated!!
I had more time to work the problem and I got it fixed. I opened up the housing to see the wiring and control board. It turns out one common wire was terminated correctly on the board BUT the other common wire and ground wire were terminated backwards straight from the factory.
The white wire (common down in my case) was terminated in the ground terminal on the board and the ground was terminated in the common down terminal while the red wire was terminated in the “correct“ (common up in my case), which in fact had made the dome rotate in the opposite direction of the arrows on the switch before I rewired everything. So in the end all three wires were terminated incorrectly on the board.
One other issue I had was that as I tested each wire at its terminal on the control board each wire end broke off. So I had to strip each wire to get a good new connection.
To sum up, I ended up releasing each wire from its terminal, the ends broke in the process, i stripped the wires, I terminated the wires (common up, common down, and ground) in the correct terminals on the control board and viola it works like a charm! problem solved.
I hope this might help someone, but it seems like a very rare case.
