Van as built. It is an "off road" van so has plenty of ground clearance.

A quick bit of research has indicated that the heights quoted are in an Australian Standard and an ADR. However, they only apply to ball couplings for on road use. It seems other couplings and off road trailers have no such limits.

I would have thought all vans have to be onroad just to reach the offroad.

Hi All.
Repeat post as I think I put it in the wrong place (apologies).
I too have a MY14 in need of an answer to what I think is a low charging rate (less than the cut-in voltage of 13.2 volts anyway).
I'm interested in what make/model of battery isolator you used Stuch to solve the problem. I too am working in uncharted territory as far as the 'experts' are concerned and don't think the expense of a DCDC charger is necessary. My needs are really to power the fridge in my caravan. Any trickle charge to the caravan battery would be a bonus.
I have found this which may be the answer:
http://www.jaycar.com.au/products_up...680_manual.pdf


Hi all.
Here's a question for those of you that have installed a power feed for their fridge/battery for their caravan.
My MY14 CRD 12 pin 20 amp caravan power socket doesn't work. (7 pin trailer lights ok)
The reason is relatively simple.
Redarc battery controller 'releases' the current at 13.2 volts.
The charging/alternator voltage of my jeep is 13.1 volts. Thus no power is released.
It is due to back to the installer but I'd like to know the best solution before hand.
All professionally done and very neat.
Power and isolator all installed in the battery compartment.
All hooked up direct to the battery.
I'm concerned if the 'solution' is to get an ignition feed from other parts of the car to run a relay which in turn then upsets any of the canbus system (out of my league at this point...).
Any help appreciated.
Cheers
Andrew

Re: The Towing thread

Take the Ign feed from the aux power socket in the cubby, or near the sub woofer. Use a Controller that is compatible with a variable output alternator.

Re: The Towing thread

Hi All
Follow up from my earlier post.
Had the jaycar isolator fitted today replacing the redarc with the 13.2 volt cut in.
Fits (just) beside the battery on the floor of the battery compartment.
Power to the 12 pin plug now. Set to cut in at 13 volts.
The trailer lights dimming issues was a less than perfect earth which has also been rectified.
Had a loan V6 petrol MY 14 today. The difference back to back with the diesel is significant.
Hope this has been of some help to those buying a new JGC. The joys of being first. Think I'll let them install a few rear cameras before I get mine. Heard they had arrived in the country.
Cheers
Andrew

This is my post from another forum, worth copying here:
Hi Andrew, great that the issue has been sorted....
I do find it strange that your battery voltage is so low however, and also that it seems to differ from the earlier models - but still uses the same AGM battery.
As I understand it, an AGM battery charges at 14.2 to 14.8 volts, and floats at 13.2 to 13.7 - I've metered our 2012 CRD and it shows numbers in this ballpark. Our van has AGM batteries charged by solar panels, and the Morningstar controller shows similar numbers as well.
Obviously you haven't had an issue with battery charge but I can't see how your main battery can be getting correct charge if it sits at 13v with the engine running.
If your vehicle is typical of the 2014's, then with a feed to a van for fridge or charging it could be that voltage drop may be an issue,with such a low start point, and again I can't see how van batteries will be charged - unless a DC to DC charger is used.
Perhaps someone could educate me.
John

I would very surprised if the MY14's only charge to 13volts, I believe the MY14 still use an Absorbed Glass Mat (AGM) battery, the AGM battery needs to be charged @ 14.3v to get them fully charged, if your GC is only putting out 13v then your battery is going slowly flat.
Most modern vehicles use alternators that slowly ramp the volts up to full charge rate @14.5v, this can take up to 10 minutes.
Have you been able to have other MY14's checked?, our MY11 starts out at about 12.5v then ramps it up to 14.3v after about 5 to 7 minutes.
I would be having your dealer check with the jeep tech line what the charge rate should be, 13v is tool low to recharge an AGM battery after short driving (city) and your probably going to have electrical problems as the battery volts drop, modern vehicles do weird things with low voltage. I would guess you have a faulty charge regulator.

Thanks Paul.
Will keep an eye on it. I have seen the charge rise to around 14 volts (and thus the original regulator would have cut in). I was told it varies however depending on the state of charge of the battery.
Perhaps a brand new battery in a good state of charge is sending the signal to drop the alternator input (variable alternator) and thus put less load in the engine as an efficiency measure?
Nonetheless, the new isolator gives me options to vary cut in and cut off voltage.
Thanks again.
Cheers
Andrew.

Re: The Towing thread

It may be worth checking the cable size. Did your sparkie use battery cable? I get the impression many Aussie auto sparkies use 2 to 3mm wire for the light stuff and 6mm for the heavy stuff as a matter of course. Even a relatively small 6B&S battery cable has about 2.8 times the copper of a typical 6mm cable. If he used 6mm auto wire then you will certainly need a DC-DC converter. Another thing is that he may have used the body as an earth return to save on wire. While this works, it is not a good idea. The earth points are prone to high resistance and can promote corrosion.
