Hello everyone, I’ve been a new member of your forum since today and brought a big problem to the start, unfortunately. I have a Mercedes 814, Bj 1985. When driving over very bad road the charging control went on and at the same time the rev indicator went off. Shortly afterwards everything was back to normal. That went like this again two three times, until then the rotary zalometer stayed out and the charging control is always glimmering, whether the engine is running or not. At the same time he does not give the ignition key meh r free when I turn off the engine. Unfortunately, my guess that a relay is defective has not been confirmed. Have tried a new one on all the stecj places. I have not yet been able to discover driven cables. Does any of you have any idea what this might be about? I am curious and hope for you! Thank you very much! Rayk
