Re: The Towing thread

A voltage sensing relay would require the least trim removal. You'd probably need an adjustable one as the difference between the fully charged AGM battery and the alternator output when it's in reduced output will be minimal. Maybe a few hundred millivolts in worst case...

Check Intervolt and Redarc.

Cheers,
Steve

You can pick up 'ignition on' from the torch charging point. Doesn't need full trim removal.

it does look daunting to do on the instructions but it is actually quite easy to do. there is a little bulge in the side of centre console covered by the drivers seat. it seems to have been put there just to thread wire through for guys like us. it comes out near to a join in the carpet so it is easy tohide the wires.
best of luck with it.

If yours is working fine, power to you. :thumbup:

For sideways movement, a dab of weld on the side of the insert and filed down to suit should do the trick. In an emergency, stick your wife's credit card in there to take up the slack.

The wiring, which is in the US cars, used for a simple Brake Controller fitting is also not added to our cars.
The towbar, which is the bar that gets bolted to the chassis is supplied by Best Bars in NZ and sold as a Mopar accessory. The Hitch, is the part which slides into the towbar and incorporates the Towball.
If you order a Towbar from the dealer, as part of your purchase, they will install it and supply a hitch and towball, as well as a 7 pin flat socket. The towpack is not standard on any of the models.
I understand us tow bar is not compliant with Australia regulations. But will it fit?
What is the consequence of non compliant towbar installation. I don't really worry about insurance (for accidents caused by towbar) at this stage.
Thanks

Hi
Is that US hitch on Aussie GC?
Thanks

Have you chased quotes though? I only paid $460... it seems like a lot of work for the gain, plus you're deleting an asset from the donor vehicle. What about the bumper cutout? :thumbdown:

Just my thoughts...
Hi
Is it US version towbar or Aussie one? It looks like I could buy US Mopar hitch for less than AUD300 shipped to perth. I am not sure its worth it. But I am not towing any big staff atm.
Thanks

Re: The Towing thread

Mine is an Aussie spec by Best Bars NZ... same as everyone's here in Oz.

Would you really choose a non-compliant towbar? I'm no safety nanny, but that seems a big concession for the savings.

Cheers,
Steve

I've been searching the forum and other sites to figure out a good way to connect an auxiliary battery. Most seem to say that a dc-dc converter is the best way to go especially in the case of controlled output alternators,,as it maintains a high enough voltage for charging, and for fridges etc.
However, a disadvantage is that the charge current to the auxiliary battery is limited by the converter, to a lot lower value than if it was directly connected to the alternator when the alternator is producing at the higher level of its voltage range ( resulting in a lot more driving time to charge the auxiliary battery.)
So the question is: Is there a way (or a suitably intelligent converter) to connect the alternator,directly to the auxiliary battery when the alternator is producing a suitably high voltage, but via the converter when the voltage is reduced by the management system?
A related question: given that the alternator output is controlled by the electrical load at any given time, then if the auxiliary load (eg a fridge) was sensed by the management system, then there would be less need for a dc-dc converter to maintain a voltage high enough for the auxiliary load. Since the load must therefore be sensed somewhere after the battery, is it possible/practicable to connect the auxiliary battery and/load after the point at which the load is measured (vs directly from the main battery terminal). If so, where?
And then: are the power outlets in the JGC, especially the rear one, connected in a way that the load they supply is measured by the management system?
Thanks, Russell
I am planning to put a second battery as well.
Below is just my thought. Any knowledgeable person is requested to fix if anything wrong or not practical. The first easy solution to what you said is adding up smartpass by cteck (40amp) to dc dc charger in parallel. My cheaper solution is putting two basic isolation solenoid (2x $20) parallel. they are controlled by three position switch (1 off 2) on the panel. Start with direct charge from alternator then about 45min switch to dc to dc charger by flicking the switch. Back up (in case I forgot) is I can buy an adjustable timer delay relay ($8) that switch over to dc dc charger after time automatically. Actually this timer got two time set up. I could charge starter battery for 5 minutes (that means disconnect between two batteries) then direct charge from alternator for 45 min then through dc dc charger after. Minutes are examples, they can be adjusted. With this set up I can expect more than 40A depends on state of charge. Another good thing is you can add up a battery monitor and watch and switch over to suitable position. The decision here is current not voltage. Because my dc dc charger can handle only 20A, I will charge directly as long as it stays above 20A. As batteries are charged up to certain level or alternator Volt goes down for some reason, The current goes down under 20A and switch it over to dc dc charger.

I am not sure yet. Just being a bit tight on budget atm. Where did you get your bar for that price?

Re: The Towing thread

It was part of a large ABN transaction including two full sets of bash plates. The dealer who looked after me best and had all items in stock was Wanneroo. I also had a very competitive quote from CruisinOn, also in the Wanneroo area.

Cheers,
Steve

Its was the the Aussie one, I was in melbourne during the easter break and was able to pick up a tow bar from northern motor group for $474.30. I have to say the Aussi one is very solid tow bar very good quality welds and fits perfectly.
