Abstract
A method for generation of a low test voltage is used for the purpose of detecting an ionization current in the spark gap of an internal combustion engine. The voltage is generated by a controllable ignition magneto (5) arranged in order to charge (2) an ignition capacitor (4). The voltage is applied (3) to the primary side of the ignition device after generation of a spark and after the decay of the spark, after which the ionization current is detected (11) on the secondary side of the ignition device.
