Installed a high Amp Anderson Socket under the bonnet
Today I installed a 350A Anderson socket under the bonnet.
I have one in my Defender and therefor already have a couple of devices with such a socket on the end. So I wanted one in the Disco as well. I am going to use it for all sorts of devices, mostly using more power than interieur sockets can handle.
With the 350A rating, it can even be used for jump cables or a winch but I am also going to use it for an air pump and a charger.
There was an unused mounting which made it quite easy to attach the socket to, without doing damage to the car.
Used 35 sq mm cables directly connected to the battery.

Nice, quick Q's
Is it attached to the main battery or Aux battery?
Do youhave a rubber cap for it? Is there a danger rainwater etc might sit on the two connectors & leak through into the wire as it's positioned like that?

It is attached to the main battery. If mine has an Aux battery I didn't find it yet. Just have the car a couple of weeks . The socket drains itself because it is all open on the inside. Since this socket can cope with bigger cables than the ones I used. the insulation will also go in each pole's connector thus making water ingress from above impossible.
I am afraid I haven't thought about this type of water ingress before though. So by coïncidence I have one cable that is proper protected and one cable that isn't

A few people have chosen to install a second battery in the void under the similar cover on the opposite side of the car to the main battery - not sure if its the same sides on a LHD car Never needed to know I guess
Once you chuck out the 'alarm' box you should have enough space to fit one. (Alarm will then work using the car horn which is louder!) Probably advisable if you're going to be running loads of extra bits.A happy childhood ... is the worst possible preparation for life.

I have mine off the Main battery and fitted into the rear bumper - trying to jump start a car or run a winch off the auxilary battery can blow the fueses in the dual battery charger system.
also added a small connector on the front bumper to run camping stuff etc from Aux battery Duncan

Obviously run winch and jump start off main battery I took it if he's using it for a 'charger' then aux might be a good idea. Plus its all Bodsy's fault, he brought it up ..... A happy childhood ... is the worst possible preparation for life.

when you say 'small connector' ?? been thinking about such a thing but never really found a reasonable plug other than round trailer type. What have you used?

Good thinking. I am a navigation freak with multiple gps's floating around the car. I must allways make the choise between permanent power so they keep their fix but with the risk of draining the battery when not using the car for a few days, or using an ignition feed but that will drain the bluetooth's gps internal battery sometimes leading to strange results. An aux battery wouldn't be a bad idea. something to put on the never ending wishlist .
I really like the looks of that Anderson Plug you installed.
Of what, or how did you make the mating piece of the clip that is attached to the Anderson plug?
I have a left hand drive as well and there is that unused female clip, (I will call it that), on the air filter "box" so I wondered what or how you made the mating piece as I have been thinking of attaching something to the clip.
Also in my gallery, I have a few pictures of my install of a second battery under the cover of the empty engine compartment space on the steering wheel side of my LHD.
Not that it really matters I suppose, but per the link below, Anderson makes a rubber sort of cover that goes over the open ends of their various plugs and gives them kind of a nice finished look. They even come in different colours.

Hi berndv, Besides jump starting, I’m curious as to what would draw that sort of power?
BTW, if anyone is considering setting up to jump start, the standard 50 amp Anderson plug is all you need.
While the constant current rating for these plugs is 50 amps, they can safely and effectively handle much, MUCH higher currents for sort periods of time and they are perfect for jump starting.
Note the same thing relates to cable size for jump starting. You don’t need electrical substation size cables to jump start.2008 TDV8 RR Lux + 2009 D4 2.7

Tim,
There's a comment in this thread that says to jumpstart off the main battery, not the aux - is this correct, and what would be your suggested way of connecting up an Anderson socket and cables to provide such a jumpstart facility on a D3 ?
Thanks,

Jimbo, Connect Red Cable to Positive, connect Black cable to Negative (or to good negative chassis point) Connect other end to the Anderson plug & it should sit nicely under the cover as long as you don't have too long a cable.
Just need to make sure that you have a set of jump leads that you do the same connector on one end to
I just use the positive from my Aux battery (as it's already earthed) and a single jump lead to the main cranking battery Bodsys Brake Bible

Hi Jim, if your specifically setting up to do lots of Jump Starts for other vehicles, then wire to the cranking ( Main ) battery.
But if you are setting up the Anderson plug to primarily run accessories, like inverters or compressors and so on, then wire to the auxiliary battery and if you need to do an occasional jump start, it will work fine.
Even if your auxiliary battery is a dedicated deep cycle type battery, the occasional use to jump start is not going to have any detrimental effect on a deep cycle battery.
If your jump starting your own vehicle from your auxiliary battery, you pretty well need to fire up the motor as soon as you connect the batteries.
If you are jump starting someone else's vehicle or from someone else’s vehicle, you should connect your auxiliary battery to the other vehicle’s cranking battery and then let good vehicle idle for at least a few minutes to get some charge back into the flat vehicle’s cranking battery before you try to start the vehicle.
By doing it this way, you are not try to charge a totally flat cranking battery and and start the motor at the same time and if it’s your vehicle, putting some charge into both the auxiliary and cranking battery before trying to start the motor, again improves the chances of starting.2008 TDV8 RR Lux + 2009 D4 2.7

@ Bodsy - ta, makes sense.
@ Tim - ta, also makes sense. Only going to be doing the occasional jumpstart, rest of the time I'll be running an inverter/other toys, so I'll wire it into the aux battery.

oops didn't catch your question up until now. I used a bit of alluminium strip, Dremeled in shape and some nuts as spacers.
@DriveSafe: apart from jumpstarting, I do have a portable winch and an air pump. Also for these the 350A socket is a bit overrated but I used this one because there was already one in my Defender and thus also have them on the other end of my devices.
Still thinking about putting a hidden winch on the Disco. might use this connector to connect/isolate it.
A battery switch might be a better solution but would mean leading another thick cable from the battery and finding a proper spot for the isolator.
Since a winch would not be used very often, using the anderson connector would be workable for me.
