Using Jumper Leads on d3 TDV6

[Rockylizard]

Gday...
Been reading the FAQs and was wondering where to connect jumper cables on the D3 TDV6 should I have the need?

+ve to battery +ve/-ve to ??? on D3.

I'm assuming connecting the -ve of the jumper lead to battery -ve is not wise?
I read the Thread about how to make/obtain 400amp cables etc. Just interested in where to connect should I need to.
Cheers

Does a D3 have a dedicated +ve jump start post on the firewall? I seem to recall they do, but it is quite some time since I looked under the bonnet on one.

Jon, You are thinking of the RR Vogue (LM).

John, For safety sake i would do the same as the FAQ's & connect the +ve side to the battery terminal.
The -ve side, i again would go to the cam bolt under the vehicle as described in the FAQ. If u look under the passenger side of the vehicle you will see a large threaded bolt coming towards you, connect to this.

This is if YOUR vehicle has the FLAT battery.

Cheers.

Hi Sniegy,
As that cam bolt is mounted on the chassis, is the D3/D4/RRS chassis earthed via a cable? I ask as the D2 chassis is not earthed directly, only via drive-train bearings and steering ball joints and bearings particularly don't appreciate high electric current.

A question..... what if we are being typical helpful Land Rover drivers and we are using the D3 to jump start someone else....... how do we connect the jump leads?

On the "D3" only it would be safe to place the jumper cables on the +ve & -ve terminals of your own vehicle & then fit the +ve side to the other cars +ve terminal & the -ve terminal to an Earth bolt somewhere in the engine bay or where ever one can accessed.

regardless of the type of vehicle I always use the following procedure. (assuming they are of the same voltage of course)

check how much power the receiving vehicle has (usually I just turn on the ignition and turn on the headlights to see what lights up and how well)

hook up the positive cable directly to the battery positive terminals (or the dedicated jump starting point) either first it doesn't matter.

hook up the negative cable to the good batteries negative terminal and keep the other end in my or my assistants hand.

connect the other end to a solid earthing point on the engine preferably to the same chunk of metal that the startermotor is bolted to

start the good engine and run it for at least a couple of minutes at high idle while I check that the receiving vehicle is receiving power (turn the ignition on and the headlights again to check brightness) then start it up.

disconnection is the reverse of hookup.

Good point Blknight.
A bit more detail is always a good thing.

To be honest, I am not sure I would do it with a D3. I definately have no knowledge relating to jumpstarting with a D3.

So why am I sticking my oar in?? In all previous vehicles that have had a computer of any nature under the bonnet, I have always jump started with the rear demister on, and headlights on. Theory is that this would remove any spike that might cause nasties to anything electrical under the bonnet.

I can only say, I had no malfunctions using this method. Whether it was due to this strategy or not I cannot say. Of course now all the jumper leads have anti spike protection, so this may no longer be relevant.

Hi Graeme,

I am pretty sure it is, just cant remember where i saw the cable go to/from!

I am also sure the D2 was earthed, there was an earth cable from the engine to the firewall behind the block. I know the D1 had a cable behind a body mount.

You got me thinking now....
