Abstract

The testing circuit has a control element (12) with a control contact (13) connected between a supply voltage node (11) and a first input contact (5) of the ignition coil (1), the second input contact (6) of the latter connected to an earth node (15) and the switch contact (9), controlling the switch element (4) connected in series with the ignition coil primary inductance (2) between the input contacts, coupled to a reference voltage node (17). A measuring device (19) is connected across the ignition coil input contacts. An independent claim for a testing method for an IC engine ignition coil is also included.
