Is it possible to obtain a wiring diagram for my Winchcombe?

Don't want to mess with anything but very useful for fault finding and general interest. allthumbz

There should be one in your manual, which being a new van should still be with the van. If nor contact AutoSleepers

Hi. The wiring diagram in my handbook is a schematic and does not cover all the electrical items. When I bought my 2013 Nuevo ES I was told I could have the wiring diagrams for the audio, 12 volt and mains. On taking delivery Auto-Sleepers did not supply these wiring diagrams as they said they were Intellectual Property. I cannot see how the wiring connections between items can be Intellectual Property. The wiring diagrams should be supplied with each motorhome so that when there is a problem it can be rectified by the owner or dealer, especially if away on holiday.

Totally agree up!  As I  have bought the thing you would have thought I have the right to the detail confused3 obviously not:shrugg: 
Never mind eh?

OK misunderstood. 

If I was in your shoes then and they wouldnt disclose information which was related to my safety for a product I had paid a lot of money for I would persue the matter.

I had no problem getting the circuit info for the van and I downloaded the Sargent info from Sargents site. This info with what I already knew gave me all the info I needed

Having had a good roll around under and in my Neuvo Lancashire I can see why they cannot supply wiring diagrams as the wiring is so appallingly bad it is obviously done al fresco with each model. Having said that, "I" own my vehicle and feel entitled to know how it is put together. There is nothing intelectual about AS wiring in any form!!

Agree again Chris. I am going to slowly piece together all the info I can find from the component manufacturers and then apply that visually to the vehicle wiring layout and see if  ca make 'some' sense of it all.

I believe I am correct in saying that AS supply the schematic and layout of the new vehicle to Sargent who then design and build the wiring loom.

You will notice that all interface is by connector and any excess length of loom is bundled rather than being re-terminated. This is so AS can call on Sargent for warranty in the case of fault.

From my experience handbooks for electrical appliance and the AS schematic are delivered with the vehicle. If you want detail of the looms you contact Sargent who I have always found really helpful.

I have always found the information supplied perfectly adequate for operation and fault finding on my vans.

The grey area in some vans can be the physical location of some items such as relays so it is worth doing some research when you have time so if a fault does occur you know ehere to look.

Yes do agree with you Peter now I am getting my head around the systems. 
Sadly being an aircraft engineer but trade I have the 'need' to know what, where, how and anything else. Bit sad really but it's a habit scratch head So still need more info confused3 

Il will manage though allthumbz

Unless the Mercedes install has changed you should find:

Leisure Battery with its fuse and a temperature sensor under the front passenger seat.  Vehicle battery and a useful toolkit under the carpet in front of the passenger seat.  There is a switch to disconnect the vehicle battery if the van is stored for a long time - see Mercedes handbook.

Under the drivers seat is the Sargent EM50 that is the interface between the van and habitation electrics.  That is where the vehicle battery is connected to the habitation circuitry and it houses the fridge and step relays, provides 12v feed for the fridge and reversing camera and has the interface to the central locking.  Three fused input feeds are in the fuse box in door side panel under the drivers seat and the circuit fuses are on the outside of the EM50.

The split charge relay is part of the main Sargent PSU.  The waste and fresh water level indication looms connect to the psu as well.  There are inline connectors in both of those looms that are taped in but can be a cause of problems.

I'm not sure what water/heating system you have but the supplies will be fused in the Sargent PSU.  If you have the Whale water system I suggest you search for the various posts on this forum.  If it is a Truma fill system you need to be familiar with the pump selection in the Sargent control unit and if you have gravity fill you are lucky!

Any solar panel should be connected to the Sargent PSU which will both regulate and share the charge between both leisure and vehicle batteries.

If you have any other questions just ask.
