I have an Liesure Bay hot tub with a G2 circuit board / control from 2003.
I was having problems with OH codes after bringing my spa up over the summer. I ended up sending my circuitboard and controller out for repair. The OH code issue is now fixed.
I now see a problem that neither of the two lights are working. These lights haven't been turned on for 8 months. When pressing the light button on the controller, I hear a clicking coming from the board.
BTW...I rechecked all the connectors based on the diagram on the circuit box (including hooking up the 4 prong light cord back to the circuit board).
So...is there any testing multi-meter testing I can do on the light outputs (or lights themselves)? I have tried measuring low voltage DC coming from the prongs on the light board but I get nothing.
