Hello to each other! My wife drives a Suzuki Swift, which is currently causing us to break our heads. He was several times with my screwdriver, which now doesn’t know any more. The following history: Ribbed belt torn, repaired. After that he remained lying down 2-3 times, just went out during the ride, that cleared itself for the time being through an empty battery. So into the workshop. Exchange of the alternator. Here he has also remained after a day, battery empty. After two days, I lay down. Now I put on my own hand, and measured a few things. Battery voltage without alternator: 12.45 volts Battery voltage without alternator: 12.3 volts Voltage on the alternator, without battery: 17.8 volts When I connect the alternator to the battery, it starts to chirp. Sounds like it’s running at full load. Power in idle mode without consumer: 1.5A current with switched on consumer: approx. 40A I took out different fuses with running engine, no change. Also on the control unit behind the center console I pulled the plugs, no change. Unfortunately I don’t know any more advice, and hope someone can help us.
