Gday, Can anyone tell me what's involved in transferring my portable ARB air compressor that's carried around in the toolbox, to fitting it under the bonet? I don't mind having to open bonet to use compressor.
What would be the best way to hook up the compressor to the battery? Could it be permanently connected but have an on/off switch?
Is anything else needed?
Thanks
Barnesy

As far as I know you can just mount the compressor to any suitable location you can find under the bonnet and hardwire it to you battery via a switch which can be placed any where you want it.
On the dash if you have a location in the front grill for the hose so that you don't have open the bonnet or if you don't mind you can always just open the bonnet and use the switch on the compressor.
I think the main advantage to a permanent installation is that you can also install a storage tank so that you can have a reserve of air available to use straight away and the compressors is always on trying to fill the tank turning off when a certain pressure is reached.
I am not sure but I think you need the tank if you want to power your diff lockers but I am sure others with tell me if I am wroung

Yep just hard wire through a swith to the battery with a suitable 25 amp fuse close to the + terminal of the battery. Make sure your wires can handle the load, peak is 20 amp I think.

Time, what's wrong with just using the existing wires by cutting off the alligator clips?

The existing wires would be fine to use to hard wire to the battery, I would do this thru a relay and run the relay active back into the cabin if you want a cabin switch or just use a weatherproof toggle under the bonnet.
If u want to use to for the lockers the fitters will set it up so it is always on and the ARB compressor has a small tank of its own that is switched with a pressure switch and the system plumbed into the locker/s.

Pretty much covered in the last post. A couple of advantages happen. You get better performance from the compressor as the power cable length shortens considerably so less voltage drop for a start. As
well they tend to overheat slightly less.
Make sure you get is separately switched and fused.
ARB used to make some mounting brackets for them as
well if I remember correctly so it may pay to have a chat just in case.
Remember to regularly
check all wiring and the filter, particularly if you do any water crossings

Barnesy,
Consider mounting the compressor under the front
seat, driver or passenger which ever you prefer.
If you put it under the bonnet it will run hot. It has a thermal cut out and
mine would only run for a couple of min if I had been travelling at highway speeds or working in the sand for any length of time.
If you put it in the cabin it will stay cool and clean. The other advantage is that you can keep the hose connected all the time.
Mine runs under the floor mat and sits behind the middle row of seats. It is easily accessed which saves a bit of time it can also be used for pumping up netballs, soccer balls and the like while you are racing to get there in time for the start of the game.
The other advantage is that when you have been playing just a little too long and need to be getting
home quick or you eill be in even more trouble, you can get passengers to tidy up the hose while you are steaming
home.

The disadvantage of mounting these compressors in the cabin is thay are noisy. Used with a diff locker, it will come on at unpredictable intervals, possibly startling the driver.
Another disadvantage is the solenoid valve may spit out diff oil,
mine certainly does that, and this might make a mess in the cabin.
For the above reasons I have the compressor mounted behing the left headlight in the troopie. Never had a heat related problem with it, despite the 6.2 V8 donk under the bonnet.
For under bonnet mounting I would recommend to rubber mount the compressor mounting bracket, otherwise it may transmit the vibrating noise via the chassis and on my old troopie this was certainly noticable until I fixed it.

My in-car version of the same beast came with a complete harness - a relay is involved for supply, with illuminated switching in cab. Seems the existing wiring should be ok for a simple hookup - main issue for me would be a decent fuse immediately after the supply from the battery ! As others have said, plumbing a reserve tank into the air line is good (I made one with rated PVC piping - has been faultless for 5 years +) - gives you more 'blow' when seeking to clean/blow parts down during repairs etc. - you ca get a snap on nozzle to replace the tyre inflator for this. The in car model has a 100 psi cutout too - you can turn the pump on and forget it.

I will have to find out if my model has a pressure cut-out. Do you have any pics of your reserve tank?
Is it a simple matter of having a small tank in the air line?
Obviously ensuring it won't leak through the hose connection when the hose isn't hooked up.
Thanks

I bolted
mine to the side of the cargo draws in the back and ran an air fitting through the filler bit beside the draw with a switch next to that. That switch I ran through a relay so I could get away with a lighter switch, and it then goes through a pressure switch.
I don't run a locker so oil coming back up the line isn't a problem.
Mine was second hand and I just used the wires that were on the compressor and wired them into my fridge plug in the back. It was an under bonnet installation for the guy that had it before me, but it didn't seem to be too dirty and the filter was OK. It would be an idea to have plugs to stop water getting in the air fittings though.
