FAQ

What exactly is the task / function of the component?
The ignition component generates, distributes or switches the high or primary energy required for combustion within the ignition system. It is therefore a central link between supply, triggering and ignition spark formation.

How do you recognize a defect / typical symptoms?
Defects are indicated by a lack of or weak ignition spark, misfiring under load, rough running or thermally dependent starting problems. Insulation damage, contact corrosion or age-related resistance changes are common.

How do you check / test the component?
The supply voltage, primary and secondary resistance are tested if specified, a spark pattern with an ignition tester and the condition of the housing, connectors and insulation. In the case of distributing components, the rotor, contacts and carbon tracks must also be checked.

When should it be replaced?
The ignition component is replaced if the measured values are outside the specification, cracks, flashovers or unreliable function under temperature. Preventive replacement is advisable if the insulation is brittle or corrosion has progressed.

How do you check compatibility?
The OEM number, ignition system type, number of cylinders, plug configuration, resistance range and mechanical fastening are decisive. Cable lengths, high-voltage outlets and shielding must also match the system.
