Caravan wiring diagram - commercial design?

[Deleted]

There's plenty of generic van wiring schematics around the net, however does anyone have a good commercial vans detailed wiring diagram they would like to share with me?

Sometime back I fixed a factory wiring fault in a mates new Windsor, which entailed me making a scribbled rough diagram; to work out how it all came together.

I am endeavouring to produce a detailed 'How To rewire your 70's van for the 21st Century' ... or something like that and will model it on a simple commercial offering.

Hi wahroonga, what are you after, low voltage or high voltage diagrams or both.?
I have a copy of Jayco (USA) wiring diagram, very simple one but probably all that is needed for average van. I designed my own circuits but they are rather complex as I have a lot of different gear to normal + solar and power available from car. can help out with extra info if you like.

I'm after a diagram of both.

Most vans now have an integrated 12v/240v system with inverters and inverter/charges incorporated.

This is a schematic from Rays Caravans. home.iprimus.com.au/rfh/battchargers3.html



I was after the next level.

There's a number of safety and design issues to be dealt with, as well as the selection of industry tested components etc.

Anyone? Or do we all only own old bangers

This is the Jayco wiring diagram. It says USA but has 240 volt input!!

Thanks Frank

This appears to a diagram of a 240/12v power pack plus optional battery and solar system.

Pretty decent unit 35A @ 12v = 420watt

Any further details or diagrams?

Particularly the details of the various units. e.g.

240/12v charger, battery, solar regulator etc.

The power supply used by Jayco is I think a SEATEC unit, ( not to be confused with the excellent CTEK multi stage chargers.) it is basically a transformer. not good for charging batteries unless fitted with a regulator.
I have a Ctek Multi XS 25000 (25 amp 8 stage switch mode charger) powering my van and wired directly to the 100AH deep cycle battery as well as a Morningstar SS20 controlling the 110Watt solar panel input. Only have 240 volt for 2 power outlets and the Ctek. everything else is 12 volt. 14 fuses and 3 circuit breakers provide protection to the 12 low voltage circuits in the van.
I have designed my own circuits but cannot put them up as yet as they are still in the form of rough sketches that only I can decipher.
Lighting is mainly LED and 2 low voltage fluorescent globes. refrigeration is by way of a portable chest fridge (compressor type) that uses a mere 1.01 Ah. ( about 35 to 70 watts). I can stay off mains power for several days with this setup which is what I intended to have when I rebuilt my(VV) Franklin as an up to date touring van.
