Wiring up compressor

Hi,
That is why I brought a wire back to the battery box from the other end of that earth wire which is bolted on to the gearbox.

Here is my set up. I have two compressors under the drivers seat permanently mounted and both connected directly to the battery under the passenger seat (this is my starting battery). First off is the ARB compressor that runs my lockers, then there is the big twin ARB Compressor which is linked to two tanks under the floor.

The big twin ARB compressor has a huge fuse holder which required me to cut a rather large hole in the battery box.

I also added breathers to the air compressors which I have sitting between the cab and the ute canopy.

Thanks for that .....is there any reason I could not just attach the black negative wire on to the same bolt on the chassis where that wire is .......

Hi,
None at all. I brought the wire up to give me access to a good earth
for future use.

I avoided this by cutting the fuses out, and attaching lugs.
I use a MIDI fuse and fuse holder instead of the factory maxi fuse (Slimmer design, same amperage)

You could then use it for multiple accessories.

As for extinding the wires, just use the same gauge wire, it should be OK as long as you are not extending it another 5m. Fuses as close as practical to the battery is best.

Fitted one of these at the rear of my truck to plug in my portable compressor to
.......nice bit of kit
Question .....given this plug in the back is primarily to drive my compressor is it better to hook up its wiring to the main cranking battery ....or to my second battery ....which I run my fridge from

Thanks again

I wired my compressor to the second battery.
Reason being that the battery controller should prevent the cranking battery fom running flat, so all non critical electrical loads I've put on the 2nd battery.
Best make that decision yourself, as it really depends on what else you are planning to run off that socket, and how much you plan to use the compressor.

Given the amps compressors pull I always run the engine when using the compressor.....

Thanks for that ......will probably hook to second battery then ....just to be safe
And run engine while I air up .......mostly use the compressor for all 4 wheels after sand ....or on long trips as required ......my ARB compressor in a box has a "no load" of 13 amps and " load " 23 amps ...........not sure how to translate that into how much battery drawdown it would use on airing up 4 tyres ........my second battery is an Opima yellow top ....? 50 amp hours ?
