Hello! I have the following problem: When I turn on ALL consumers on my legacy, the charging voltage collapses to approx. 12V, I am experienced myself in car mechanics and electrics. Everything has been measured and the car was already at the dealer and at a free workshop. No one found the error. Of course, LIMA and battery are new and also the belt is ok and also all ground points and plugs are ok! Ultimately a mistake was suspected in the wiring harness. And what should it be? I have bought an identical subi to change the wire harness. Before I tested it again and it has the same phenomenon as my car!!! I guess now that the generator is too weak on the chest. I think it has only 70A. Who knows a solution, or if there is stronger light for this model. On the housing unfortunately there is no power indication. I am for j ede help grateful!! Greetings Ludwig
