FYI... Balboa does not make spas, just control systems. but that is enough info to begin a troubleshoot process...

• do you have anything displaying on topside control panel?
• Fault codes?
• When you say no power after connection to circuit what do you mean exactly?
• Have you checked for burned system fuse?

The 4 terminals are actually only on 2 terminals! If you look closer, you will see that 2 terminals are actually on SAME post. So... place a wire into one spade terminal, and then Cross over diagonally with the other wire. it does not matter which wire goes where. Just be diagonally across from each other.

Or... replace the bearings, they are what is loud.
