Hi- I have a Sundance Cameo hot tub that was installed in 1992. I have been troubleshooting a problem where I turn on the hot tub and the breaker trips after about 10 seconds. I think I finally narrowed this down to being my heating element. However, as of today, the control panel on the top has no lights. I have checked that the ribbon cable is plugged in and the LED on the outside of the control center is lit so I know it is getting power. From the looks of things, here is the board I have - http://www.spacare.com/sundancecentury400digitalpcbrd.aspx Leaving the hot tub unplugged for an hour or so didn't seem to help. Any thoughts on what this could be? Thanks RIKIL
