Definitions

  • the circuit comprises a transistor T1 whose base is connected to the terminal Kl.15 of the ignition coil via resistor R1 and diode DI.
  • the collector of the transistor T1 is connected to ground via resistors R2 and R3.
  • the emitter is connected to a terminal Kl.1.
  • the terminals KL1 and KL15 are the primary terminals of the ignition coil with KL15 on the battery side such that the voltage at KL15 is the battery voltage supplied via the ignition lock.
  • the junction between resistors R2 and R3 is connected to a first input of a comparator 10 via line L1. Signals supplied to the comparator 10 are smoothed by a capacitor C1 connected between L1 and ground and limited by a diode D2 connected between L1 and ground.
