Which model Thetford of fridge is it ? ( Fault code 10 is a 230v problem on the Thetford N3000 series)

Could it be the negative side of the wiring that is faulty ?

I believe that there is a door management control unit (central locking etc) under the dashboard on the right hand side which has a multi-plug which could be worth checking that it is pushed fully home. The control unit , which is linked to the BCM , should have a coloured data identity label on it. The fuse for this unit is F36 (20a) in the dash fuse box (bottom row , far left)

That Compass Drifter is a C class Motorhome .

Have a look at the items in the Sargent shop , the replacement kit shows both the 5x screws and 5 x ( threaded ? ) seals that are used to fit them .

The replacement kit for the water level sensor system used with an EC155 / B includes 5 x studs , so , as suggested by Keith , the other sensor studs may be causing the problem. If you are sure there is only two studs Sargent technical department may have other suggestions if you give them a ring.

The sensor used when you have a EC155 / B are studs that go through the side of the water tank and replacements can be found in the www.sargentltd.co.uk shop (water/waste sensors section , with the replacement studs shown at the bottom of the list) also if you look at the power systems section in the shop you will find the EC155 /B with links to its fitting instructions that show these water level sensors and their connections. Their support / help centre / knowledge base may also be useful for information.

The type of water / waste level sensors you have will depend on which model of Sargent PSU (ECxxx ? ) you have fitted in your Motorhome.

You could also try magnumvs.co.uk who may be able help with a replacement .

I have also got similar readings at the moment, with the sun out, through the solar controller doing its job, the leisure battery voltage should drop back a bit when it gets dark .

On my 2015 Peugeot (X290) the parking lamps are turned on by moving the ring on the lighting stalk to position O then to dipped or main beam headlamps but I do not know if the X250 series are the same.

The leisure battery to the EC155 cables should be brown/blue (positive) and white/orange (negative) , but If you go to the Sargent website and go to support / help centre / search articles / EC155B power control , the EC155 install information found there has the wiring information , including colours of the leisure ( and starter ) battery connections

They may have used the leisure battery power supply into the EC155 as a connection for the solar controller , to save having to run a separate cable all the way back to the leisure battery terminals from the controller.

Are you sure that the EC155 has a solar input connection that can be used instead of going direct to the leisure battery from the controller? (as some other Sargent PSU units have), it could be worth checking with Sargent Electrical 01482 678981 or check at www.sargentltd.co.uk support section.

It could be worth replacing the engine/gearbox to body earth cable (or adding another) which can look ok but have been known to have a fault (resistance ? ) causing odd electrical sensor faults

To add - Have you turned the control panel master switch on . as required , for the awning light switch to work.

There may be a fuse on 12v fuses section on the PDU marked control panel that you can remove and then refit. to try to reset the digital control panel , this may reset the awning light control.(if that is what is needed) Also are you sure that you replaced the wires in the same places as I think your light may be an led type which must be connected the correct way round to work .

Have you checked if the fuse is ok , it could be with the other 12v habitation fuses on your PDU , you could also try re-setting the digital control panel by disconnecting it and then reconnecting

I do not know what setting to use for your Swift Motorhome ,I think it could relate to motor revolutions , If it is any help ,my step (On an Autocruise van conversion) is a single letter box slide out type and is set at 45 (the set button can be used to alter it when in advanced settings), Sargent should have the information you need and it could be worth a call to them ,they are normally very helpful.

If you find that a clean up does not help it may be that the step run time has been altered/wrongly set , the advance settings in the PSU select/set display can be used to alter this.

You should find the step operation wiring at socket P5 on the rear of the PSU.

I believe that the step operation is built into the EC400 PSU, the step settings should be able to be seen in the advanced settings section of the PSU (Press and hold the yellow select button) . Sargent should be able to help with more information if needed 01482 678981 (support section )

If your PSU is a Sargent unit , the step may have been controlled through it,( Depending on PSU model )

onecal , I believe that may be a Truma Combi 4E/6E PCB you have shown with flash codes , as the heater/boiler that is/was faulty is a Truma Trumatic C6002 unit do they use the same board ? The Trumatic C6002 has a red and green light on its control switches to indicate a fault.

I do not know if Fords are the same , but , later Fiat Ducato based campers have a Door management control system which uses a different module depending on which doors are required to be operated with the central locking . (it is also linked into the BCM)
