xenon2000 Posted November 21, 2018 Report Share Posted November 21, 2018 I have a Balboa EL2001 Mach 2 circuit board and ML700 topside panel with aux top panel. I am trying to pinpoint if I have an issue with the topside panel or the circuit board. The board was replaces under 2 years ago. The top panel acts like everything works, icons change like it is working, but nothing actually turns on. None of the 3 motors and not even the spa water light. All the fuses are good and I don't see any visible damage on the board. I would love to be able to unplug both top panels and test if I can get the circuit board to turn anything on. Is that possible? Quote Link to comment Share on other sites More sharing options...
