Hi. Urgent question.

Need to confirm that the Jayco 12 pin plug / socket uses pin 10 for ESC.

We had our car wired for the 12 pin as per Jayco diagram but sold the van along with the wiring diagram, ESC manual and my printed details have been lost.

Just delivered car to auto electrician who will change the 12 pin to a 7 and two Anderson plugs, one of which is dedicated to ESC....but I can't remember, or find the details for which pin was used for ESC.

Did a search here, no go. Found the latest ESC manual and it specifies pin 10.

Any one with a better memory than me....or more accurate info. (Mine was wired in 2014.)

ESC is on pin 2.
Pin 10 is earth for pins 8 9 11 & 12

Thanks.

Will see if auto electy has discovered that....tomorrow.

Why then does the alco ESC manual,state that 10 is the one?

You will have to ask Alco that.
Jayco uses pin 2, the black wire, for positive for the ESC and pin 3, the white wire, for the earth.
Jayco uses pin 9 for positive for the fridge 12 volt when the van is under tow, and pin 10 for the fridge earth.
Pin 2 on other trailers is generally used for the reverse lights which are not used on vans.

Get the auto elec to wire power to an anderson plug with adequate cabling.... And get the van supplier to wire the ESC with adequate cabling to a matching plug as well.
Just reread your post and realised you are getting the anderson plug for the ESC.....Alco page states Pin 10 as the earth and doesn't state which one is the positive?

Unfortunately in the caravan/trailer world there are NO standards

Fwiw if I was wiring a car for esc I'd wire it through a driver controlled switch where I could disengage it. There's has been serveral occasions where being able to briefly disable it would be advantageous and much safer .

Got all that but my issue is what were they requiring for the 12pin in 2014, which is when my car wiring was done!

and I passed all that on to the new owner when the van was sold...so should have kept a copy in the car but it didn't occur to me...

Wiring requirements have changed since then...eg Alko now specify a separate Anderson plug, which they didn't require in 2014.

So...I'll leave it to the auto electrician and his trusty multimeter.

Just thought someone might actually have the 2014 wiring diagram which Jayco issued to owners in 2014.

Oh well!

All done.

Still not sure of the Jayco configuration but then, I no longer have a Jayco with 2014 wiring.

I'll ask when I pick up the car and post if anybody else is likely to have this issue.

The multimeter must have worked ok.

Thanks for the suggestions.

ALKO do not require a separate Anderson plug. I have the ALKO ESC unit on my 2016 built StarCraft, and the van came from the factory with a 12 pin plug. (Jayco haven't ever changed they 12 pin wiring configuration). Only reason I changed from that to 7-pin plug plus 2-pin plug was because I already had my vehicle configured that way.

My ESC works via the 12 pin. The only stipulation was that it had its own power run directly from the battery, which I did, and the ESC works well.

Pin 2.

It's not a requirement apparently but a strong recommendation....and I wanted to change it (pre this nonsense) as I wanted the option to disconnect if I felt it was necessary.

On rough roads

Without having to disconnect the entire plug, including brakes.

And the auto electrician said the "wiring recommendation" from Alco had changed several times in the past few years....and that comes from a specialist caravan electrician who does multiple setups every week.

Anyway, I'm now ready for the new van in that area at least with a very sensible solution to my prefetence for both input and output from the grey (non ESC) plugs on both car and van.

and I'm over it.

Whatever else others do is up to them.

Fair enough mate. Just that its a bit hard to provide someone with advice when they seem to change what they are after...

After all you did say


Hi. Urgent question.

Need to confirm that the Jayco 12 pin plug / socket uses pin 10 for ESC.

And you also said

<snip>
Wiring requirements have changed since then...eg Alko now specify a separate Anderson plug, which they didn't require in 2014.

<snip>

Which apparently they don't, according to their own published literature...

http://alkoesc.com.au/wp-content/uploads/2016/05/ManualV13web.pdf

All they say is "The ESC should be connected to the tow vehicle using a standard 12 pin plug or 2 pin connector. The layout for a 12 pin plug varies between manufacturers, contact the manufacturer of your caravan to confirm how your caravan is wired. For off road use it is recommended that the ESC is connected to the tow vehicle using a 2 pin plug such as a 50AMP connector to disconnect the ESC for periods of extreme off road driving."

(I'm guessing that not too many full sized vans will be used in "extreme off road driving" scenarios...

Excuse for making these statements, but don't you think its important to put CORRECT information out there. considering others may make their decisions based on what they read in this forum?

Not worth an argument!

I'm certainly not justifying myself as I asked a question ....not intending to initiatiate a debate.

You can be as pedantic as you wish. As said, I'm over it. Question has been answered.

And yes I can read the ESC destructions and would have read the manual if I'd had one!

not wanting to buy into any "bad feelings" but

it is obvious from the beginning that @Dobbie was not sure / did not know / did not have a clue as to how the wiring is / was done
he "thought it was pin 10 (but was proved wrong - oh well........"
he was told by the Sparky information that may or may not be correct - but as he is not a "Sparky" himself - why would he doubt what he has been told

yes, @Doc it is ALWAYS better to get as much, and as accurate amount of information as possible, but
sometimes people are NOT specialists in that field, so can only describe how they know best

I did have a PDF from ALKO that said not to use an Anderson plug, which I thought was funny, as most (or some) put them on an Anderson.
I thought they recommended not to because - if someone forgets to plug it back in.......are they liable.........

anyhoo

unlike some sites, I personally dont like the
"he said / she said / they said" idea

again, not wanting to step on anyone's toes or spoil their enjoyment of this great site

I'm not after any bad feeling either but.....this is a friendly forum and, for a while, I thought I'd accidentally wandered onto another forum where the tone is more critical and patronising and where posters often don't read before they instinctively post.

My intention is definately not to be confrontational and I don't think I was either wrong, confrontational or against the spirit of this forum.

But I could be wrong....it does happen ....as I was with my memory of where the ESC was wired to the 12 pin plug.....but I do thank those who helped.

8-)

Hi Dobbie,

I will assume that majority of your negative comments were directed at me - after all, I was the one whose replies you seemed to take particular exception to.

If so, please show me where I was being critical or patronising or against the spirit of the forum or "wrong" as you put it etc), so that I may apologise appropriately.

The comments I made - if you take the time to read them - were in the interests of clarifying what you posted, so that the correct responses may be posted.

If you are able to point out where I was rude or otherwise unfriendly in any way, please do so.

I look forward to your response, because it was certainly not my intention to be negative - only to get YOU and OTHERS the correct information.

It was a general comment..if you think it's directed at you.....so be it.

My question was very specific....and it has been answered.

Your contribution did not add to the answer.

As said, I'm not after a Stoush. That is not the point of this forum, and definately not in the spirit of sharing, helping those who ask questions or seek advice. That I have done to the best of my ability since I joined.

If your feathers were ruffled by my comments, so be it. You certainly ruffled mine by suggesting I give incorrect information.

I can see no point in pursuing it ant further....so have a good day.

Hi Dobbie,

I'm sorry you feel that way.

I offered an apology if you were able to show where I offended you. You now saying that I "ruffled your feathers by suggesting you give incorrect information".

I apologise for that inference if that caused you offence. It was not my intention to suggest that you post/ed incorrect information.

Can I please ask one thing - you said "It was a general comment..if you think it's directed at you.....so be it"

Then you said "You certainly ruffled mine by suggesting I give incorrect information"

So did I or did I not offend you? I am trying to apologise...
