Hello together. I bought a Chevy Caprice bj.83 to build up a bit. Unfortunately, the previous owner has cut the complete wire harness. Now I’m already sitting there to swirl the part together again. Only I have a problem with the front light. H4 bulbs are installed, electricity also arrives. Only it doesn’t light up. If I turn on the main light I also have power on the ground cable,in the dipped light not. If I use the bulb directly with the battery mass verb Ind then it lights up. I still have everything running over a charger because I don’t have a battery yet. Everything is going on back. Meanwhile the flasher relay goes again, no idea why. Thanks already for your answers.
