SeeLevel Tank Monitor Issue

[marsharini]

Our tank monitor is not giving any readings, including battery level.  Just wondering if this has happened to anyone else.

Some background info, we were in for service at the end of April and the tanks read prior to the service.  One service issue was a replacement water heater and I’m wondering if something got knocked loose somewhere between hulls.  Unfortunately for us our pickup from Service was on a Friday close to closing time and they couldn’t get out fast enough so we didn’t find the problem until later in the day.  We were able to stop in on Monday afternoon and one of the service techs took a look at it and even tried a new monitor panel, but no success.  The tech did mention a possible pulled wire somewhere but they didn’t have the time in their schedule that day to find a fix.  
 

If there’s an easy fix/solution we’d like to try that before we haul it down to Hohenwald.

Is there power to the unit? Does your water pump switch / indicator work?

I would check everywhere a service person may have worked to see if there are any pinched, broken, or unplugged wires. 

Are any other devices not working, check fuses, etc..

"Track "IT" down!

Yesterday I towed Twist home to prepare it for an upcoming trip.  As per usual - I plugged the 30 amp shore power cord into a 15 amp extension cord which (in turn) was plugged into a GFI outlet on the side of the house. 

All was working as it should until about 4 hours later it was time to plug in a vacuum cleaner in order to start cleaning the floor of the camper - yep, the vacuum didn't work!  All other things were still working (or so I thought) but plugging and unplugging and checking the GFI - both inside and outside the camper yielded no joy.

OK - time to check fuses - OK time to take apart the circuit breaker panel - OK, time to check the house circuit breaker panel - OK, time to take a break and actually think about what is going on.

Finally (I can be a bit slow sometimes but this was really starting to p... me off), it was time to start getting serious.  So, starting have already noted that 12 volt things still worked AND with the inverter on the 110 volt interior items worked, I felt that the "problem" was isolated to the 110 volt shore power.  But, in my mind I had already checked that and there was no problem with fuses, circuit breakers or connections.  BUT - lets actually TEST these things to make sure that they are actually live at each connection point.  Sure enough, the extension cord was bad.  No sign of melting, burning, corrosion, loose connection, or anything.  Also, no one had tripped over it nor disturbed it in any way since I had first had things working.  Eventually (probably during some dark cool rainy winter day I'll get that extension cord back out and see what the problem is.  But, for now, the problem was fixed by simply getting another cord and getting back to work.

Everything else is working as it should.  We’ll have to wait until we get home to check further. Fortunately for us after 11 years of ownership we know how long we can go between dumps and fills.  Battery monitoring can be done manually until we get this figured out.

I would get a hammer and beat that extension cord FLAT..... then I would cut it up in little pieces, braid it into a noose and hang it in full view of the other extension cords as an example of what will happen if they pull the same sh%t.

I believe you hit on it here! New issue often comes from last service. I can't believe you were there and OTT Service would not fix an issue they likely created in your scheduled service one business day before!

They tried a "new monitor panel." Did they first check the fuse? You have a hull a little older than ours but maybe this circuit is wired the same. Our DC panel has a fuse titled "Water Heater Tank Monitor" (see pic DC fuse #7). Perhaps we're getting closer now! 😎

This 15A fuse might be blown. If so, your HWH would not have 12V to fire up on LP. 

If you have hot water, I'll bet they pick up 12V from the HWH wiring and if so, there would be an inline fuse between there and the SeeLevel system.

It's really bad electrical practice to wire inline fuses at random locations in the basement! RV manufacturers do this often and when I find fuses around the Oliver basement, I move them to a new +bus I wired under the rear dinette seat, so I know where they are, have easy access and never have to reach down under again!

Look around for an inline fuse, starting at the HWH then going towards the tank readers or the SeeLevel panel. Hope you find it quickly!

I have a manual for model 709 and 709-PH.  
 

 

The battery level displayed is determined by the voltage supplying the SeeLevel panel. 
 

 

As others have said see if it’s getting power. You said the tech plugged a new panel in and it was dead also. I can’t believe that the tech didn’t also check the fuses as that would have taken a few minutes. I would check the voltage going into the panel and work back from there  

 

This schematic is for 2018 LEII hull 313 so it might not be the same for your hull
