Story of a w140 m104.
Last week I drove my car to my daughters home.After visiting I put key in to start nothing but a click.Tw0 weeks prior to that the car did the same thing when one battery cell was dry.So again I assume water.Nope battery was fine.
These cars for some reason won't jump start.So I call my son and tell him to bring my 83 300SD battery.Put battery in and she fires.
I get home take the weak battery and put it in the SD ,she fires right up.

What happened? Why w140 won't jump?
