Owl Arb twin under seat install

I find this the best solution for the Arb in a Ineos.

I like the idea but not prepared to pay $500US for a bit of bent plate.

Also I would prefer the top lip to be bent to return under the seat to stop dirt/stuff stuff falling in gap

I have the tjm pro under the hood with the catuned bracket.
Use it with the morrflate air magic box to digitally set pressure to two tires at once. Worked absolutely great in Moab!

I think it's about $100 more vs when I ordered it, but I may have gotten early pricing. Super nice. 100% duty cycle.

Hi. I just did the same and bought the ARB Twin Compressor. Do you have any photos or details of the wiring?

All,
I am in the process of installing the OWL Vans compressor under the drivers seat and I have a couple of questions that I hope someone on this forum can help me with. So here we go: The OWL kit comes with wires made up for the switch, but it doesn’t have an ignition trigger and it appears that once installed the compressor will be able to run with or without the ignition on. I am planning to wire the power supply (2 - 40 amp wires) to the 5th open position in the 2nd Littlefuse busbar. I have ordered the stud, etc. I think the 2nd Littlefuse busbar pulls from the Auxillary battery so in theory if I did leave the compressor on without the ignition it would only drain the auxillary battery? Can anyone confirm this?

Alternatively, I looked at the Agile Off-road installation and the run a trigger wire to the fuse box and use and open position to run the trigger switch for the compressor. This will make sure that the compressor won’t be able to turn on without the ignition.

Based on the wiring diagram from ARB, posted above, it would appear that I can likely install the unit with the OWL kit, but to have it trigger off of the ignition I would need to run a separate trigger line to the fuse box and then to the middle of the switch?

On the OWL kit - I am not entirely sure how the power supply feeds the switch, but I cam guessing that there is a power supply pulled from compressor that is always hot and the switch then triggers the relay to run the compressors. Any help with this would be appreciated.
Thanks

I'm thinking of buying an ARB Twin Portable to use with my Wrangler.

Ok - so did a little more research on the compressor in person and it appears the wiring diagram is not entirely accurate as there is a hot 12V in the 3 prong connector showing only Purple and Black. There is also a Red hot line that will feed the switch. This is what OWL did - they used the hot line out of the compressor to fee the switch so you don’t have the ignition trigger. In this installation you are hard wired to the battery for the compressor and not dependent on the ignition. Assuming the battery load is taken from the Auxiliary battery that would be OK with me in the event I left the switch on, assuming I had an air leak. I know they all leak at some point so eventually you will have a dead battery.

So my options are to run a “trigger” line connected to the ignition, per the instructions from Agile and ARB, OR does anything know if any of the Littlefuse bus bars are triggered by the AUX switches, etc? I GUESS - I could run the trigger to one of the AUX switches on the interior, but not sure I want to run the wires? Just an idea - would appreciate any thoughts.
Thanks

I'm a KISS kind of guy so I would prefer to run the compressor on it's own circuit. That way it's not dependent upon having a key in the ignition. I tend to be diligent about vehicle shut down so I'm not too worried about draining a battery. If you are then mount a lighted on/off switch that you can see when exiting and you should b pretty well covered. If you're anywhere in the vehicle or near by you should be able to hear the compressor turn on if a leak develops. Omitting a tank would also reduce the possibility of leaks when away from the vehicle as well. With the Ineos dual battery system I don't see how it matters where you're drawing power from as the batteries are always connected and trying to equalize - so to speak.

I just use my Anderson style output at the rear of my Grenadier to power my compressor, only works when the motor is running so the full voltage for better power to the compressor. Tanks are pointless IMO, I know i have one in my camper for the air suspension, unless you are using a massive tank which is ridiculous.

Agree with the tank comment and I have no intentions of installing the tank with the twin compressors that are 100% duty cycle.

For now I have decided to go with the OWL install directly to the battery (the power for the trigger comes from the switch harness - there is a positive output on the harnes, but the wiring kit from ARB doesn’t use that as the trigger), but I am going to go ahead and run a trigger line from the spare fuse slot to the compressor so that if I want to change it to trigger on the ignition I will just swap the trigger line on the switch. This wil be as simple as just pulling the switch out and swapping out the positive trigger lines to the switch.

I have the ARB dual suitcase and the built-in small tank is really nice. I agree with not fitting due to space constraints, but if you have a tank you will like it!

ARB portable mounted in a 2-seater. Still to be connected and tidied up.

Hi. I'm not a brilliant mechanic or electrician but I'm preparing my Trialmaster to have the Twin ARB Compressor mounted in the jack space utilising the Black Sheep mounting kit.

I think I have the main parts figured out (thanks to other members for their input - and an electrician is coming later this week to do the connections. I have a couple of questions that I really need some help with:

(1). Do I connect the compressor to
(i) The started battery
(ii) The auxiliary battery
or (iii) Does it not make a difference which.

(2). Which is the starter battery and which the auxiliary?

Many thanks

Gwynne

HI Gwyne,

There is a 25A outlet behind the auxiliary battery which can be used. This is wired to the starter battery but that should not matter because you usually have the vehicle running when inflating tyres as compressors draw a large current.

I tend not to use the auxiliary battery because I don't want to potentially affect my warranty with non factory wiring. This will change once my warranty expires and I'll revert to a traditional dual battery setup.

 

[Gwynne]

Thanks Znarfgh, but a single compressor draws 40A and I'm assuming the twin 2x40A ie 80A.

How do I identify which is the starter battery?

The ARB twin should be wired directly to the starter battery. This is because the alternator supplies currently directly to the starter battery and the engine should always be running when using the compressor. It can draw 80amps when under load which is very high current. If it is wired to the auxiliary battery then it is a longer current path as power from the alternator has to first go through the starter battery before reaching the auxiliary via the Ctek combiner. I don't know the position of the starter battery in right hand drive Grenadiers. It is behind the driver in left hand drive versions.

 

[Gwynne]

Many thanks TCMColorado. Most helpful.

Anyone know where the starter battery is on a UK RHD or how to identify it?

(1) Most people connect the compressor to the main (starter) battery, but it can be fitted to the aux battery. My compressor is fitted to the 5 stud busbar. If the compressor is wired only to work when connected to an ignition source, it really does not matter. Since the compressor only works when the car is running.

(1) Rok Dr Guide shows you which is which. On RHD cars, the main battery is on the passenger's side. Screenshot from the Guide:
