 Hi Paul on my Jayco the black wire is the aux wire,I pulled the black and the white wire out of my 12pin plug and fitted them to a Anderson Plug ,I had a problem with the 12pin plug getting hot on the Aux wire and melting the plug on the Aux terminal only,I think it was my fault because the wire was loose in the terminal,It won't come loose in the Anderson plug,no trouble since.

 Hi Lance, does that black/aux run the fridge or the charger to the house battery?

Aussie Paul. 

I have that Doug thanks. It is the actual Jayco wiring that I need to find out.

Paul on my Jayco that aux wire (black wire ) runs the fridge  while I am driving and charges the house  battery, battery charger only chargers the battery when on 240 volt, also the aux wire charges the breakaway battery as we'll  when driving,hope you can understand what I am saying.

 Ok Lance, yes I understand that. I wonder what the pink wire does? This is a pic of the other side of my Jayco 12 pin plug.

Guessing by your last picture Paul, your aux wire is the pink one,if you have a test light plug your plug in and stab the pink wire ,make shore your vehicle is not in reverse,and also it looks like the big terminals have been used for earth and aux,witch makes sence.

Thanks Lance, a job for me tomorrow then.. I still have to work out what the black and pink wires do.

Still at it!!! Pink drives the fridge when tug engine is running. Our Dometic RM 2453/2553 fridge does not have any indicator for when it is working on 12 volt or AC.

I cannot as yet work out what the black wire on pin 2 ACTUALLY does. No power from Tug at any time and have not followed it through the van. 

We are heading to Apollo Bay this Thursday to use the second 5 days of our Travel Auction voucher. I will take multimeter etc and have a look while away. Looking to free camp on the way home on north end of Lake Colac, Meredith Park. All this new grandchild baby stuff has tired me out!!!

Paul if that black wire indercates on the photo as being reversing lights, put your tug in reverse with ignition on don't have the motor running and check if you have reversing lights,and a free camp on your way home  from Apollo bay ,try the one at Inverleigh ,toilets over the road near the pub.

 Did that Lance and no power. I don't think van has reversing lights?? I had better double check, so stand by.

Ok on Inverleigh.

Aussie Paul. 

A birds nest has been found.... A bit of pen to paper schematic is in order for future diagnostics!!!

Holy Moses that is spaghetti at his best :

Paul if that wire what you call No 2 is the one for your fridge while driving Its not the most ideal thing to have your fridge is using close to 20 amp /hr and that cable is far to light for that
I would recommend to install a separate cable from your main battery 6B&S  with a Anderson plug as Our Indian Chief told you  Uncle Doug
and the same size cable (fused ) from house battery to fridge


  Cheers John

 John, the pink heavier wire definitely runs the fridge, I reckon the black number 2 wire is for the Setec charger to charge the house battery. I will find that out while we are away this weekend. There is a group of female spade connectors not being used as well. Bugger that we can't get wiring diagrams from Jayco.

Hi Paul

even that pink wire looks a bit thin for a fridge to me mate

I would for sure change it to 6 B&S

Came to Apollo Bay Thursday. Someone forgot to check all interior drawers etc locked, and the drawer with the glasses in came out onto the floor!!! My fault, I am told, for going around corners too fast!!! Anyway no real harm done. We will make fewer and fewer mistakes as we get our rythym going.

Surprised that battery voltage was down a bit. Thinking about it I reckoned the 240v Setec not working. Thought I must have mucked something up with all the wiring I was mucking around with earlier in the week. About to growl at myself when I realised the the fridge and Setec are now plugged in to a power socket behind Eril's chair now that the club lounge is out. Reached down and turned the power point on and the lights brightened up!!!!!!!!

This is our 5th trip away since Feb and gradually getting to know ins and outs of the rig set up.

Empitied the toilet cassette and now the red light is still on!! another little job to sort. Eril has gone to a market and I am resting and conducting smallish jobs around the place. Beautiful day here, about 22 and gentle breeze. Waiting for AFL to get under way and of course typing this post!!!

According to my ESC book, pin 2 is the ESC positive and pins 9 and 10 are for the fridge.

BTW I have a Jayco 2013 Starcraft

Safe travels

I assume ESC is electronic stability control. Pretty sure we have not got that Phil.

Aussie Paul. 

Interesting. Today I pulled the Setec out to try and follow some of the 12 volt wiring for the fridge and the Setec charger. Tagging stuff when I a sure of its function. 

No 12 volt at fridge until vehicle started. Good news.

Dark beat me so more checking tomorrow.
