    Hello, the problem is as in the subject. Does any electronics cut off the starter with a weak battery? You do not even hear the electric strike, the voltage on the battery does not drop when you turn the key on the starter. The second thing is whether the factory alarm cuts off the starter in this car?

    Battery charged?
    Starter briefly starts - starter relay good?

    I'm charging the battery right now, it happened suddenly. After turning the key in the ignition switch, the voltage drops to 11.5 V

    Replace it with another battery and check the weight of the engine - canopy - battery, it should be about 13 V.

    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

    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.

    Starter for regeneration.

    And what cuts off the factory alarm on this car? Starter or something else?

    Does the car alarm have an immobilizer function at all?

Topic summary

The discussion revolves around a 2001 Jeep Grand Cherokee experiencing a no-start condition, attributed to potential issues with the starter, battery, and factory alarm system. The user reports that the battery voltage drops to 11.5V when attempting to start, indicating a weak battery. Suggestions include charging or replacing the battery, checking the starter relay, and assessing the starter's functionality.
