Thread: Wiring up compressor

which variant of the defender?

generally.

you want the fuse close to the battery and you want to run both the positive and the negative back to the battery or to a major earth point such as the body earth strap or a body earth connection fitting and NOT an internal earth distribution block/junction connector itself as that can cause some issues in some circumstances with overloading the earth wiring from the block/junction connector to the body earth point.

If your compressor is in a box, and you want to keep it that way, then just install an anderson plug flush mount socket like this:


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.

Thanks chaps .....it's a new model 2016 ......

Where would I look for the body earth strap ?

That plug looks good where could I source one ....

Earth strap is on the inside of the chassis rail directly below the battery box.
The anderson plug flush socket is made by trailer vision and can be sourced fairly easily on ebay (search flush mount anderson). About 25 clams shipped.

I saw someones install where they mounted the flush mount socket on the top of the battery box beside the passenger seat. It's an ideal location if you don't mind drilling the holes in your new ride. Spec it up with some fatter cables (16-25mm2 cross sectional area) and you dcould make it a jump start socket.

Great ....thanks for that

Hi.,
The earth strap on mine goes to the gearbox, so I ran a wire back up to a seat rail mounting bolt in the battery bix.
On mine the earth strap connection to the battery is not suitable to get another wire on to it.

I wouldn't be jump starting using a 50a Anderson......you could probably get away with it but it's above its capacity.

If you running a positive to the battery than I would also run the negative to the battery......I length of twin core instead of separating the cables.

Yeah you're right, the Anderson SB 50 is probably a little underspecced.
Would depend on the size of the engine, wiring used, type of starter motor etc.
The 50A rating is continuous, so intermittant use at higher amperages is permissible, but to what extent is the real question.

There is some good info on their website SB? 50, SB50, Small Anderson Plug, Anderson Power Products
