Patent ID: 7212005

Claim:
An ignition coil tester, comprising: a control module; an output electronics for testing the functioning of an ignition coil, the output electronics being connectible to a diagnostic tester, the ignition coil including a primary winding and a secondary winding for generating an ignition voltage, a field guide plate, a plug connector, and a secondary output; a housing and first spark plug dome for receiving the ignition coil; an interchangeable insulator; and an interchangeable adjustment metal sleeve serving as a connecting piece from the secondary output to one of a gas spark gap and a spark plug, by which a diameter of the first spark plug dome is adjustable to a diameter of the ignition coil and of the second spark plug dome in an internal combustion engine; a capacitive sensor attached to the adjustment sleeve for uncoupling an ignition signal wherein the housing has at least one of a first aperture in a region of the capacitive sensor for a measuring line of the capacitive sensor and a second aperture in a region of the field guide plate for a signal line of the field guide plate; wherein at least one of the first and the second apertures is electrically insulated by a high-voltage insulation and one of a spark plug and a gas spark gap can be switched into an ignition circuit.
