Caravan wiring

Darren,

What type of fridge does the caravan have: 3 way or compressor type?
The reason I ask is that if it's a 3 way then (in my opinion) it should NEVER have been designed (by Windsor) to have been powered through a small pin on a flat 7-pin trailer plug.......I probably wouldn't even have done that with a compressor fridge due to the length of the cable run.

In my opinion there needs to be an Anderson plug used for this AND the negative/black wire needs to be run through to the same earthing point that the fridge is bolted to on the chassis. The reason for that is that the negative connection is just as important and is currently relying on a relatively thin black (?) black wire to earth everything back to the tug.

Judging by the diagram, I can only surmise that the 2 red wires are piggy-backed onto the orange wire somewhere behind the panel where they disappear.

Either way, it looks a bit shoddy to me!!!

If you're not entirely sure of what you're doing, it might be wise to enlist the help of a friend or, as a last resort, take it to an auto sparky.

Good luck,

Get it wrong and you may have a fire and lose the lot. I would be a bit stronger than Roachie and go to an auto electrician and get them to do it. Them show you what they have done.

If you do it yourself you risk your insurance. Not so with a qualified workshop etc.

Was it 6mm Automotive cable or 6mm section cable (Like 8 B& S) which would be the minimum for a fridge . Also wouldnt hurt to tidy up the rats nest going into the 7 pin so that wires dont cross like that as when you put the clamp on puts unecessary pressure on them. The tape is not exactly the right stuff either as that type has a habit of unrolling fairly quickly..

Get some good quality electrical tape or even better some amalgamating tape.

As said would be best to get a professional to at least have a look and give you some advice or even do the job. Electricity is not the stuff to play with if you are a novice.

First off you need to consider the fridge, if it is a three way type then you need two power circuits.

You could keep the orange wire, to power the fridge, you would then need to change the lighting circuits over to a new fuse panel which is connected to your new battery. The anderson plug would then be used to charge that battery, obviously suitable wiring and fuses would need to be installed for this circuit ie at least 6B&S cable.

If it is a compressor type fridge, then you could run a new at least 6B&S size cable from the anderson plug through suitable fuses to the new battery, the disconnect the orange at the fuse box and connect to the battery via a suitable fuse. You should also install an isolator in the car to protect the cars battery from discharging.

Another option for a compressor fridge if you didn't want to run an extra power circuit would be to use a small 10A DCDC charger, you then most likely get away with using the orange cable but it will take a long... time to charge the battery from a low state if charging via the vehicle.

Is it a BIG toe vehicle or a small toe vehicle?
