If I understood correctly, then this is where not just a shopping facility is located, but a small workshop in which a specialist checks generators and starters on site. He checked the generator for me and revealed a malfunction of the pulley (overrunning clutch). He was immediately replaced by another one. It works flawlessly! Everything was done quickly, clearly, and not expensive. I advise you to contact here! In other places, I was put on a long-term waiting list for electricians, and they threw up their hands... And here the specialist identified everything and did it just instantly! I removed the generator myself from the engine of my car, but if necessary, it can also be removed and put in place after repair.
