Hello dear community, I’m new here. Short to my person: I am almost 17 and I received a BMW E28 520i ’86 a few weeks ago. After Abi I will probably do a training as a car mechatronics engineer at a German sports car manufacturer and am very interested in old and youngtimers. Now the following problem: With my father I took off the whole cylinder head, regrinded valves, adjusted. All seals and belts changed. Now we wanted to start it today for the first time after 2-3 weeks.. No Mucks ! The starter does not turn, the magnetic switch does not crack. The ignition is normal. What can this be? I am very desperate. Thanks already in advance ! Bavarian greetings 😉
