Hi Kerim,

but that sounds like an old and weak battery. It is charged when engine runs and it brakes down if not charged. How much is battery voltage after you tried to start once and engine failed? A good battery delivers 12,3 V .

hi dr. volker
I don't know about it. But I can do something like this. After waiting 3 days, I will try to start the vehicle with an additional charge to the battery from the other vehicle before starting it. If the engine starts at the first start, the battery is faulty. how do you think ?
best regards.

Hi Kerim,

why do you not just hook up a Multimeter and check. Then you know your battery voltage. Or you just install the battery of a properly running car.

good morning dear dr. volker
I measured battery shop. They checked it.
After turning off the engine, the battery drops below 10 volts (9.7V). They said it was faulty. I will replace it. I am using varta 74 amp. Is it enough? What is the ideal of this? secondly, when I checked the spark plug cable, it says Beru ZLE 121 on the cable. When I looked at your technical information list, I saw that it was Beru ZEF 470 or ZEF 473. Is this a significant problem? Does it make a significant difference?
(my car 1976 w114 280E)
thanks
best regards.

Hi Kerim,

please check your owners manual for the correct size of your battery. ZLE 121 is the model of spark ßlug connector. What I mention is the Beru set of all ignition cables together.

thanks dr.volker , I will look it.
I came new question )
In my vehicle, there is a black-capped druckfühler, which is type 3.
First of all, what should its mounting position be? Should it sit upright on the fender? Or should the black cover be mounted horizontally towards the headlights?
second question; I bought this part from ebay. I don't know if it is set up correctly. Is there any practical way to test this? Or how can I set it correctly?
thanks best regards
