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

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.
