    Default Towbar electrics

    Hello

    Iīm a newbee from Sweden. Excuse me for my bad english

    I have a problem with my 13-pin plug.

    I have a Polar Caravan with a 7-pin plug.

    The problem is how to run the fridge and charge the caravan-battery when we are driving.
    I my caravan there is only 1 cord (6 mm2) to do this. (The fridge "takes" 120W that should be ca 10A on 12V and then we have the caravan-battery)

    Im my Vecīs plug there is 2 wires each ca 4 mm2.
    I can use pin nr 9 or 10.
    Pin nr 9 have constant current and nr 10 should have current when engine runs ( I think - there is no decatable current there)

    Can i supply my caravan through pin 9 ?

    Why is there not current in pin 10 ?

    Why canīt i detect current in the other pins (brake-light, indicators and so on) but it works when i connect my caravan

    I have asked my dealer but they canīt answer

    Best regards

    Pin 9 should i would of thought, go to your fridge as it is constant. Then the pin 10 should switch on with ignition so that it charges as you drive and turns off when ignition is turned off. 4mm should be ok as 10mm is rated at 70A max current so it should be around max of 28A.

    Thank you for answering.

    I would like to have my wires as you say in your last answer.

    Two problems:

    1 No decetable current in pin 10

    2 The caravan has no separate wiring for battery and fridge. There is only one wire from the caravan socket to the caravan- battery. The fridge is then connected to the caravan-batteri via one relay that "reads" position-lights of the caravan.

    In Sweden we must always drive with lights on (thatīs a law). Swdish cars therfore are equppied with "automatic-lights". When the engine runs the car supplies the lights with ca 10V for day-light use (for longer life )ond when the engine shuts down the lights go out. ( And if it becomes dark you must turn the knob to get "full-power" light)

    So when you connect the car with the caravan and start the engine, the position lights of the caravan turns on and the fridge vill work on 12V, and when the enigine shuts down the fridge stops on 12V.

    Iīm running this on pin 9 now and it seems to work good. I have acsess to the car-battery when I connect the caravan to tha car. And when I run the engine the fridge vorks on 12V. There is no risk for the fridge to empty the car battery due to the relay. On longer stops the fridge is working on propane.

    There is only one thing that worries me and thats the area of the wire connected to pin 9 in the car (4 mm2)

    Best regards

    the 4mm cable should be more than capable of taking the load.
