stang233 Posted February 16, 2018 Report Share Posted February 16, 2018 I have an Artesian (South Seas Spa 746L) tub that was working great. We moved it and now it is tripping the GFCI. Balboa Board MVS504SZR1B Tub is currently tripping the GFCI. The GFCI was checked and is good. Disconnected tub and turned power on at GFCI and it did not trip. GFCI only trips with tub wired. Cheeked for fault from all wires to each other and no fault. Disconnected heater (OHM checks okay) and turned power on with heater disconnected and it would still trip GFCI Disconnected ozonator still trips. Disconnected primary pump still trips Disconnected secondary pump still trips. I OHM checked the board and there is Zero ohms from Red to Neutral but 34 Ohms from Black to Neutral. Is the board faulty? A bad board seems rare especially from a gentle move. Quote Link to comment Share on other sites More sharing options...
danthespaman316 Posted February 16, 2018 Report Share Posted February 16, 2018 Make sure your neutral is wired into your breaker and not the bar at your disconnect box? Boards can fail upon being powered up. The load hitting it can can sometimes finish frying whatever has been holding on for dear life under constant load. I'd double check that all of you don't have any burns anywhere on the board. Good luck sir. Quote Link to comment Share on other sites More sharing options...
