Mystery Icon on Seattle Panel

[Arnside037]

Just pulled the Moho out of storage to go away tomorrow, only to find a mystery icon on the Seattle control panel indicating a fault.
The fault is that the panel powers on/off, the awning light works, but none of the others work. I.E. no lights, no pump and the Alde will not turn on.
Leisure battery and Cab battery work and display 100%
The EHU powers everything its supposed to and the RCD test works fine.
The Bailey manual only shows the old linear type panel, and of all the icons in the description ... this one does not appear.
Any thoughts? What is is and how do I rectify the fault.

Assume you’ve checked the fuses?

It’s showing a thermistor icon.

Displays if there are faults with the temperature sensors

As you also have other electrical issues. Could be that the Thermistor isn’t getting a supply due to blown fuse. Just a thought.

Yup. All fuses check ok.

So what's a thermistor, where would I find one/it, and how can I fix it? (Can a numpty like me fix it anyway?)

 

[KNWH]

There are probably two thermistors, one for measuring inside temp and one for outside temp.
On our 68-2 the inside one is behind the little protruding lump below the button for the awning light. Don’t know if yours is the same? Don’t know about the outside one.
I know the one for measuring outside temp for the engine is the lump under the offside door mirror, but pretty sure the habitation area will have its own.
Is the Alde panel not powering up at all? The two panels share a fuse I think.
Normally you can ‘force’ the water pump to run by holding in the button for a few seconds, even if it thinks the tank is empty. Does that feature work?

 

[KNWH]

PS When we had trouble with our panel under warranty it was found to be a faulty earth, which is a common problem apparently.
Our panel would not work at all however, so unlikely to be that, but thought I’d mention it just in case.

 

[Arnside037]

The Seattle panel does work, ... it powers on/off but gives an outside temp of -48F. The awning light works ok. The water pump only came to life when I pressed it for 10 seconds or so, the same as you found. The 12v lights do not work, nor does the Alde panel start up. Its these two that are the important ones.
If it is a loose earth, where would the problem be located? Is it in the back of the panel, and if so, how would I get the panel off without breaking it?
( I would not be surprised at a loose connection as we have just returned from Portugal and having driven over a good few miles of calçada, their cobbled pavements and streets, some connections may have rattled loose. )

As well as the control panel it is possible that one of the multi-plugs linked to it on the rear of the Bailey 12v fuse/PDU unit is loose.
If you can get the control panel off , I think that the earth cable on the rear of the control to be checked should be a white one. (along with other wiring multi-plugs)

Thanks. The secret will be is removing the control panel. Anyone done it before? Is it a case of prising it off or are there some lugs that need to be located and then prised at this point of the lugs?

Is this thread any help?

Bailey 765 Control Unit

The Control Unit above the habitation door on my Bailey 765 has become detached from the panel and has fallen backwards into the recess! It appears that to re-fix it I have 2 options 1) remove the control unit surround or 2) remove the habitation door fly screen and the panel above it to gain acc...

If your panel looks like this, I’d imagine there are plastic covers over the four marked screw holes. Remove the plastic covers with a pin or sharp object and hopefully, there will be screw heads underneath.
Alternatively, if you subscribe to FaceBook, there is a Bailey users’ group with some very knowledgable posters.

 

[KNWH]

There is a thin trim piece that surrounds the panel. This can just be prized off with finger pressure to reveal the four fixing screw behind.
If you then pull the panel out you will find about 7? different multi pin connectors behind. Suggest you take photos before disconnecting as they are some spares not used, to make it easier to put them back in the right places.
Not sure which is the earth wire sorry.

 

[KNWH]

Should have said, when the dealer looked at mine they were aware of the earthing fault problem, but they seemed to initially dismissed it and tried two new panels before, presumably after talking to the Seattle tech people again, went back and found it was the earth after all! So it may not be obvious?
My panel shows a silly outside temperature when the panel is turned off.
i.e. it is getting power and the display is showing the time, but the panel is turned off so nothing runs.
Is the display saying panel on then off as if you press the power button repeatedly?

Two more things to check if you haven’t already:
Have you measured habitation battery voltage?
Have you tried 240v hookup?

Yes I'm on hook-up at home and the battery has a full charge, and the ON/OFF works fine. (Panel ON Panel Off)
Thanks Ingwe for the advice on getting the panel off.
I think I may have the same issue that KNWH refers to, a false temperature reading + in that it seems to be only two elements of the panel not working, ie the lights and the Alde so I'm also thinking its a wiring fault. I'm not familiar with the wiring circuit of the Moho but I'll have a furkle later tonight. (Got to drive to a cemetery in Birmingham this morning ... no the dead can't wait. Well , yes they can but the cemetery staff can't. )

 

[GeoffnDee]

If you have a look at www.apuljackelectronics.co.uk cataloque / control panels / page 2 you can see what to expect on the rear of your similar control panel (The earth (negative ) cable to trace/check should be white)

 

[KNWH]

Sorry, you’ll be getting fed up of hearing from me!
The external temp on mine isn’t faulty, but when the panel is off , and you use the arrows to scroll down to it, it shows -50deg. It displays correctly when the panel is turned on.
Just for completeness, when the panel has power, but is turned off then:
Fresh water and waste water both show 0%
Interior temp shows correctly
Habitation battery voltage shows correctly
If you press the pump symbol, the light symbol or the awning light symbol the panel automatically turns on together with the pump or lights are relevant.

The fact that you are having problems with the Alde too seems odd. Two panels going wrong at the same time sounds unlikely, and is what made me ask re hookup and voltage.
Other people have said the Alde technical people are very good so may be worth trying them?

 

[GeoffnDee]

It is possible that the poor earth (negative) connection is not at the control panel itself but at a point it shares with other items (Alde, sensors, etc)

You may need to replace the thermistor fitted on the outside mirror. Very cheap (about a tenner) on Amazon and easy to fit. Mind you the Alde system fitted to my Hymer still worked when the external thermistor failed. I suspect, being a Bailey, they have made sure the Alde won't work without both thermistors, just as they have dealt with the pump when the water level is shown as "low", when the water tank sensors stop working.
