Hello! I want to get my car (type doesn’t matter) out of the workshop. The mechanic tells me that there is a problem with the battery. The car then starts with the help of a “power booster” and I drive home. The voltage indicator fluctuates when I drive home, e.g. when I press the electric windows. My guess is that the car runs on battery and not on a lich machine, although all control lamps stay out. I first measured the battery. n: 12,1 Volt Well, well, battery to the charger – charging current approx. 1 Ampere. So according to my modest knowledge, there is not much to do when charging. After about 5 hours I clamp the battery again. Interior lighting after the door opens again normal. But already when the ignition is switched on, this darkens and the control lamps only glow darkly and in the engine room is a ticker to hear. (no start attempt, in order not to break any more!) What could have broken there? The workshop only had the order to change the brake pads and check the car (purchased 4 weeks ago). I will talk to the mechanic tomorrow. Maybe you can give me a tip on what the error can be. Gruss Uwe
