Hello, I went to acquaintances and parked the car (Omega B 2,5 V6 Built. 95) quite normally. Up to here everything Ok. When I came back to the car, I turned on the ignition all the lights went on, ventilation and radio everything as always. But when the key to start went through, total power failure. As if the main fuse had burned out. I checked the three large fuses in the fuse box and the two large fuses in the triangular fuse box in the Engine compartment, but all are fine! Then I measured directly at plus and minus pole of the battery, there I have electricity. However, I do not have electricity at the cables connected to the poles! What could it be? 1. Main fuse, where is this exactly? 2. Mass cable to the body or loose? 3. Alternator defective Did one of you ever have this problem? Or someone an idea what it can be? Greeting Sebastian
