The drop test must be performed before checking the voltage
regulator/rectifier
–Turn off the ignition and disconnect the ground wire from the
battery.
– Insert an amperemeter between the ground wire and the negative
pole of the battery.
Setpoint value: max. 1 mA
– Check for power consumers, should the measured value exceed the
