My Hot Spring Grandee (old, but new to me) has a junction box adjacent to the main black control box. I'm hooking it up for the first time, and have a "spare" black wire on the spa. I'm not sure what to hook it up to. It's caped off now, and nothing is powering up-no jets, no light, no heater.
The spa uses both 230 and 110. The light is on 110.
The way it is wired now is:
Sub panel wires --> Spa side wires are...
--------------------------------------------------------- Red wire from subpanel to --> Red spa wire Red wire from subpanel to --> Red spa wire Blk wire from subpanel to --> Blue spa wire Blk wire from subpanel to --> Blue spa wire White wire from subpanel to--> White spa wire Ground wire from subpanel to --> grounded to the spa junction box.
THE PROBLEM: -->There is one black wire remaining on the spa, and I do not know what it should connect to.
Anyone know where the black wire on the spa should be connected?
