Joemp Posted October 15, 2009 Report Share Posted October 15, 2009 I have been trying to diagnose a problem with my Sundance Majesta for some time. Basically the lights shut off after about 10 minutes. Later the pumps sometimes shut off. The single biggest problem I can find is that the voltage shown on the controller with the jumper putting it into diagnostics mode continues to decline from 240 volts to 80 volts. The jets continue to run fine, but the controller turns off the LED lights and later the pumps. I can't believe that it is truely 80 volts as the pumps run fine. I think something in the voltage monitoring circuit is causing the problem. Any ideas what measures the voltage and how to diagnose and fix the problem? Thanks in advance.

otis_skywalker Posted October 16, 2009 Report Share Posted October 16, 2009 if it has a "excellent" (brand name) transformer in it, that is the problem... replace it. Quote Link to comment Share on other sites More sharing options...
mrfixit Posted October 16, 2009 Report Share Posted October 16, 2009 I am suspect that the transformer is the problem. Because it shows only 80v, I suspect the problem is within the circuit board. I am not familiar with your system, so I cannot say for sure, but the board will probably need to be replaced. Quote Link to comment Share on other sites More sharing options...
