Thread: Using Jumper Leads on d3 TDV6

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....

The negative lead from the battery in each of my D2s went to the inner guard then to the engine, but no cable to the chassis anywhere. A D2 fitted with a winch and an earth cable going directly to the winch motor will earth the chassis due to the winch cradle being mounted to the chassis though.
My 84 RRC has one to the chassis, as did my 82 RRC.

I will look at the D4 when I get a chance but as nothing requires an earth from the chassis, I suspect it will be the same as the D2.

Hi guys if you open up your D3 owners manual and go to page 298 & 299 the procedure is explained here.

I was wondering how long it would be until someone told us to go and read the instructions......

I supposed I just spoiled the thread by offering an answer ha ha

Maybe slightly off track (deviation!) but if your jump-starting and it wasn't just leaving the lights on sort of thing, it is good practice (IMHO), to pull the battery post leads off, give the clamps a cleanup with a round file lightly or grit/sand paper, and the battery posts a light scratch-up/clean up, replace everything nice and tight,check the alternator,starter,earth wires are tight, and just have a look following the wires if you can to make sure all is ok .
Keep your battery clean and clamped tight.
Remember that good point made to connect the leads on the "jumper" first to keep the sparks down and you shouldn't have a fag in your mouth or hand hanging over the battery. It's a mini bomb there if it's lead acid type.
I like to put my sunnies or clear safety glasses on if working on lead-acid batterys because they can go off and you only have one set of eyeballs.
It only takes a few minutes to get a good connection and its one thing most people forget to maintain and is the most common problem when called out for a jump-start.
There are products to cover your posts after the clean up help prevent the substance that builds up between the posts and clamps that you have now cleaned. Some put vaseline on them but this melts and with dirt build-up can cause "tracking".
All helps getting the starter spinning to the max, your alternator pumping and lengthens your battery life.
Sux breakin down .

Yep, on my D4 at least. There's a strap from the body below the air-box to the chassis on the strut tower.

I just used the leads direct from my D3 +ve & -ve to jump start a Mercedes delivery van. What a weird car that is, couldn't even see the battery in the engine bay, just a +ve lug to the fuse box and just a stud on the van body for the -ve!

Most mercs have the battery in the boot.
