Jump Leads?????????????????????

[Pietre]

OK, before someone else says it, "I must be daft", got that out of the way. Now, the question, where do I fit the jump leads to jump my car to jump someone elses, as there is no way I am moving the rear seat to get someone going. If some wise person can answer my question I would be most grateful.

 

[Koolvin]

yup! under the bonnet there are some points under a plastic cover (should be top left). Take the live (red) from there and the earth to the chasiss...

You can just see the earthing point at the bottom of the 1st pic.
hth

 

[Pietre]

Thanks, now we will see if I remember when it comes time to use them.

 

[Alps]

do you think you can use these points to charge the battery in the car if it goes flat?

For our 'stretched limo' we have a trickle charger that plugs into the car cigarette socket. This has bailed me out on the odd occassion when the battery has gone flat.

Grav's picture's are both excellent and very informative. Please don't say that is surface rust on one of the pictures though. Your car has suffered enough.

I took these pics a while ago for another thread on here somewhere.
No rust there now

Yes, you can

That Yes should not be taken as universal. I know that the W211 does not have that post under the bonnet but it's handbook contains a clear warning not to charge the battery whilst it's in the vehicle. The reason given is risk to the electronics. I've seen this on non-MB cars as well.

I'm sure the W210 was not electronic free so you should check the handbook to see if use of that post as a charging point is recommended.

Hi DieselE,
I'm a sad person with nothing to do all day and your post got me wondering about what I would do if our vehicle needed a jump start.

The manual deals seperately with the saloon, estate car versions. On the saloon it merely gives the location of the battery (in the boot) and then illustrates how to connect jump leads... Positive to positive, negative to negative (not how I have been taught)

The estate however shows a positive terminal block under the bonnet and then it advises using a body earth. I am not in a position to be nosey and I do not fancy telling wife to take the car out into the driveway so we can have a look, but it is certainly on the 'to do' list. Far better to locate these terminals in slow time when there is no pressure.

I should also mention it does state exactly what you have said about NOT charging the battery in situ. It also mentions about resetting ESP, windows, clock, and electric sunroof. It doesn't mention Tyre Pressure monitoring, but the technician definitely reset ours.

Great post and we should all really locate these jump start points.

I found mine the other day ...

Two grey metal posts with wires connected to them ... they sit on top of a large milky white plastic block in the engine compartment ..... at the back near the windscreen .....

Ah, how i love my simple car .....

You have me worried now Howard. I looked under the bonnet of mine and I dont have "a big white block" got a black one, will that do?

Is his first name Lucas?

How common to actually have it trapped under the bonnet. We keep ours nice and warm in the rear of our vehicle. Centrally heated in winter, air conditioned in summer.

It's just another example of newer not being necessarily better. To go back to the start of the thread, at least you now know that if you're ever stuck by the roadside with a flat battery it'll be a waste of time flagging down a passing W211 saloon (if john is right you'll be OK with an estate) for a jump start. The best response you'll get is "sorry mate my boot's full".

A faulty charger can damage the electronics, but one that's ok shouldn't - Also, if the battery is totally flat, I'd disconnect the negative lead before I connected the charger.

Hi Ted,
The warning is big and bold... Are you saying we should ignore this big bold warning? I would NEVER give advice that is in direct conflict with the manufacturers advice and I say this with the full knowledge that there are highly qualified folks on this forum.

I might choose to ignore advice and that is my decision, there are clearly times when we ignore advice that has no ramifications, but I have only just posted a Merecedes-Benz TSB that instruct dealers NOT to entertain warranty claims for owners that use bio-diesel and as a consequence suffer damage?

Anyway back to going slightly on topic

Your wish is my comand.

The first picture is a little dark but the little black box contains the + connection for the jump leads

This picture shows what is hidden under the + plastic lid:

When a 211 is coming towards you, look for the rails on the roof The estate car has the rails and the jump lead connections.

Then jump out of the way

Being a bit of a tight wad, I'm thinking of charging my almost flat battery rather than buy a new one.
Any advice on what to do / avoid doing? (eg touch the cables together?)
Or costs of a battery for a 96' C200 w202?
I'll have to have a look under the bonnet for these magic connectors everyone else seems to have!

cheers

mark.

In my experience once a battery has gone flat it's never quite the same again.
How old is it by the way?
