And the car alarm cuts off the starter? Because the central locking from the original remote control stopped working for me. I checked the fuses and they are ok. I replaced the starter relay with another one and also a lime. I charge the battery for 3 hours and the voltage drops to 11.9V when the ignition key is turned
Added after 2 [hours] 41 [minutes]:
The relay in the fuse box ticks when the key is turned to the starter position. I decided to gently tap the starter itself and it happened that sometimes at the moment of starting a characteristic click from the starter was heard, as if it wanted to move, but suddenly something was missing. The second important thing is that earlier, sometimes the starter was spinning during firing, and at some point it was heard as if it was disconnecting from the engine, and the rotor was still spinning.
