I have just purchased a caravan I want to use the 12 v lights in the van off the truck battery of which i have a basic dual system like a boat so do I just put power through the trailer light connections.
I can only see a 240v plug and another which is similar to 240v but bigger earth connected to a fuse box definitely not 12v. By the way its a 94 supreme getaway van.
It seems a silly question but I need to know and will be at a later date puttin in a main 12v battery on the van with a solar panel.
Many thanks Reilly

Hi Reilly
Best to get a wiring diagram from Supreme.
Mixing 12V and 240V if you don't know what you are doing is dangerous.
Regards
Derek.

I am a little surprised that Supreme (in 1994) don't have at the very least a rudimentary 12v circuit (apart from the firdge) already fitted, you looked everywhere for a fuse box? Under the bed, inside cupboards? Inside the front boot tucked away in the corner?

Thanks Dunaruna
I have 2 external inputs as for a fuse box yes i do and it appears to be connected to the external plug of which is a H/D version of the 240v and I also have 12v and 240v switches to lights and 1 internal 12vl outlet I will have a look for another fuse box etc.
The trailer lights have flat 7pin plug theres blue wire coming from the vans plug ??? electric brakes which i got mechanical brakes will l check at my truck outlet if blue is connected I have emailed supreme this arvo for a wiring diagrams.

Reilly the vast majority of caravans without a battery simply run the 12volt active (from the fridge) through the 7 pin plug requiring you to run a wire from your dual battery in the tow vehicle. It would be unusual for there not to be a 12 volt fuse block in the van somewhere if there are lighting circuits as
well.
If you intend fitting a battery & solar panel to the van at a later date I'd be running a heavy pair of leads (about 16mm) from the tow vehicle battery to a 50amp Anderson plug then new leads into the van to the 12 volt fuse block.
If not sure of wire & fuse sizing I'd get it installed professionally as it's something you don't want to get wrong.
Cheers Craig.....

Thanks Crackles
Well I got a 3way fridge.
I going through the van for a look.
I'd say My trailer plug hasn't got that active wire which is blue no 5 pin fitted job for tomorrow.
And thanks for the quick reply s from all I didn't expect it.

As Dunaruna said in the next reply - pin 2 on your plug that goes in the tug is the 12 V supply to the van. However I am yet to see any fuses, fuse block or barrier terminals in the 12 V supply in a van unless there is a battery system in the van.

No no no. Pin 5 (blue) is your brake magnets, don't play with that.
Pin 2 is what you are looking for, it is the aux pin. Should be a red or pink wire but I've seen all and sundry colors used by van builders.

Dunaruna,
You're right about the blue wire being the electric brakes & pin 2 being the aux. pin, however, the colour of the wire going to the aux. pin should be a black wire. Red is for the stop lights.

What you need now is a good heavy cable from pin 2 in the socket on your tug going to the +ve terminal of your battery (with fuse near the battery of course.)

Brad,
You are correct, black is designated for pin 2 but in the old days we always used black for reverse (before 'aux' was even thought of). Most van builders use pink these days because a lot of vans have reverse lights now. This necessitates the use of a 12 pin plug. On a 12 pin plug, pink is the standard for 'aux'.
Personally, I prefer the anderson plug scenario.

Reilly,
By your description, I would guess both "plugs" are 240 volt.
Are these actually sockets??? (ie female fittings that plugs connect into)
The second one with a bigger earth would be a 15 amp socket which is a normal requirement when connecting to a CP power pole.
The other one may be a 10 amp socket, but this is unusual, unless somebody has installed a "
home grown" connection to plug into a standard 10 amp 240 volt circuit at
home.
The only way of checking is with a multimeter. (continuity tester)
Bill.

Thats right 2 by 240v outputs female the 15 amp has the extra wide tongue and is connected to a twin fuse box which reads 415v and 15amp. I have looked every where for a 12v can't see any obvious in cupboards etc will there must be something I will have a look under van tomorrow if I get
home in time from work.
