Our SeaLevel II tank monitor is giving an error message (OPn) for all three tanks (fresh, grey & black). Research has indicated this could be one of two problems: a ground wire disconnect at one of the three monitors or a bad monitor. Does anyone have any experience with this issue
Thanks

I had some weird stuff happening with mine a few months ago and it was a simple fix. The neutral was not well connected in the panel. It wasn't obvious and I would've never known to look there had it not been suggested by another. Kill power to the trailer, go to bus bar in your panel, it should be right up front and easy to access. All I did was to make sure that each neutral wire in the panel was well connected. No point in trying to figure out which neutral goes to the SeaLevel. Just check them all. It fixed it and never another issue since.

Thanks for the tip. Can you be more specific regarding the location of the bus bar that you are referring to. A photo would be helpful if you have one.
Thank you

Were you able to sort this out? I'm having the same issue and not at all familiar with the mechanics of this trailer yet. It's brand new and only been on 3 short trips so far. I was having power issues on the last one, which was off grid, and noticed that my grey/black tank was not ever reading above 0. I brought it back home and charged it up only to then see the "OPn" readout on the monitor afterward. Not sure what's happened.

Thanks,
Holly

Hi

The neutral is part of the master electrical panel. You have three basic wires for each 120V circuit: hot, neutral, and ground. For a 240V circuit, you add a second hot lead. A cheap plug in circuit checker from Home Depot will give you a good idea if things are hooked up.
