I also have gas fumes in the cockpit but only at startup.  I don't see any indication of fuel leaks under the hood..  I've meant to also check the cold start valve on the intake although the car runs very nicely.

Hello Ralph, Yep, Rich is right. When I had my bushings replaced a while back, the lever was put in backwards but had it corrected before I drove it home. Your car looks amazing and the leather sure held up well. Looks brand new.

Rich, my car's interior is original as well and I can provide more photos although there are differences in the texture of MBtex in the later years.

I am not a mechanic, but what seems to me:

1. Battery going flat and starting/stopping as you described may be two different topics.
2. On the battery
- unless you have late US car with 55A alternator, your battery is probably too big, it should be 55AH, not 70AH - may never be properly charged and will die
- charging while engine running and illumination of charging control light should be checked (lit when ignition on, off when engine running), charging voltage with engine running close to 14V
- then, if the above is checked and fine, I would look for drains as described by other Members; the way I did it - hooked multimeter in series and removed fuses one by one

3. On starting and stopping: it would help if you describe a bit - was engine cranking but not starting or not cranking? Is it manual or automatic? Does it have CSD to control idle with gear or it is an US version? If the car was cranking and not starting - I think it is a separate issue from the battery issue.

hello
it could be the battery,

in my 78 300d I had 2 MB batteries with internal issues.

after replacing the defective MB with a new MB battery and then chasing what i thought was parasitic draw i gave up (because i could not find it) and went to a walmart battery and the problem when away.

Thanks Rich!  I’ll have a closer look.

Hi Neely,
Off topic but having recently changed the bushings  for my gear shifter I found that the stick itself was mounted backwards (apparently common mistake by mechanics)
It looks like yours is too!
It should point forward, so even in 4th gear it appears vertical - in neutral it should distinctly point toward the engine not the seats (as per the Tech manual.)
It’s easy to  remove and flip it round and I find makes shifts more positive :)

Dear friends

Please note that the only fused circuit that has power while the car is on the off position is fuse no.1…..

Therefore the only accessories that may deplete a battery are:

1. Cabin light
2. Glove box light
3. Clock
4. Or any other load attached to a T30 line or directly at battery.

In my experience our friend AAR has a defective tired, exhausted main wiring harness that has compromised insulation on main T30 lines, specially on the engine bay area.  Those lines as written on many post have a cotton resin insulation that is prone to cracking after many years of being exposed to elements (heat, water, oil).  A T30 line with compromised insulation will cause a parasitic draw form battery, and that can not be avoided by removing any fuse, since those lines per design have no inline fuse on them.

Therefore my advise is to replace that harness or make it serviced by someone with know how on that.

Best regards

There 2 versions of the water pump. The long one and the short one. Are they interchangeable?

WRe,

Your knowledge is very much appreciated. I agree that Bud's charging an arm and a leg for the set. Much cheaper to buy individual parts from your favorite parts shop. Once again, thanks for the help.

Hi,
a previous owner of my car (01/71) had problems with the police in Spain (late 1990s) because of a lack of seat belts. He has therefore received a confirmation from Mercedes that "equipping his vehicle with seat belts is not mandatory." I still have all the TÜV reports and no one has ever complained about the lack of seat belts.
I was the first owner of the car who retrofitted seat belts in 2009.
