hi was thinking putting a 12 s socket on for the caravan see you can buy a kit on ebay split charger . gotta run the cable from battery to boot any ideas on a easy route as i take it cable has to go through the bulk head and along inside the car.

On my T31 the fitter fitted a piggy-back fuse in the fuse box above the driver knee, this works OK, but direct from the battery would be much better. I was going to modify mine to go from the battery but failed to get through the bulkhead. I have seen other threads on T30 where it seems to be easier.

The only real big load on the 12S is the fridge, mine seems to work OK from the piggy-back, but on a long continental journey the volt drop could be important. Bigger the volts=bigger current=bigger cooling. (Elecrolux do a chart somewhere)

A thought however, if you have a caravan with one of those fancy Alco electric brake / stabilizers I would want as many volts on the van as possible.

I did this to my T30 last week. I ran a fused cable from the battery through the main wiring harness grommet in the bulkhead near the battery to the boot then fitted a self switching relay by Maypole. They do an ignition switching relay and one like the type I used but 30amp instead of 20amp. Look at this on eBay:

Maypole Relay - 20A Self-Switching Combi (Tec2M) - MP2881B

Maypole Relay - 30A Self-Switching Combi (Tec3M) - MP2883B

Mine has an ignition switching relay, this is wrong, it should be a voltage sensing relay. With mine the fridge is powered at about 10 amps, as soon as the ignition is set to the first position. So you can not sit with the radio on for example. I live with it but it is a nuisance. There is a potential to flatten the battery too

With a voltage sensing relay, the fridge is only powered when the engine is running, my last car was fitted with one of these.

cheers chaps ill have a butchers you can get a kit on ebay £18

hi got me relay does any one have a wiring diagram or any thing got a good idea but any help would be great cheers

Try this.....

cheers for that mate not sure about thikness of the cable from battery what it means lol i geuss i get there lol

Bigger the better to reduce volt drop to the fridge. I used 4mm (cross sectional area of the copper) thin wall insulation 12V auto cable from ebay.

so if i get 4mm cable should be ok . says ive gotta run 2 live wires from batt do the both need to be fused.
