Turn on the ignition.
Attention: The removed cable must not come into contact with the ground.
Measure the voltage between the male and ground. Set value: 100±2V.
If the voltage is approximately 6 V, then the stabilizer is installed in a mirror-inverted position, i.e. the terminals for the input and output voltages are reversed. Remove the voltage stabilizer and install it again by turning it 180°.
If the voltage is significantly higher than 10 V (normal on-board voltage, then it is necessary to remove the voltage stabilizer and check that the ground is not connected to the middle connecting contact. If this is not the case, then a piece of copper wire should be soldered between the resistor and the middle connecting contact.
