Abstract
A coil tester for testing the functionality of a vehicle ignition coil that has been removed from its vehicle includes a circuit that can be quickly and conveniently connected between the ignition coil and a battery so as to provide a current of sufficient voltage to the ignition coil. The coil tester also includes a momentary switch for preventing overheating of the ignition coil and a scale for indicating the strength of the coil.
Claims20
A tester for testing a vehicle ignition coil, the tester comprising:
- a circuit including a first set of connectors for electrically connecting to a battery, a second set of connectors for electrically connecting to the ignition coil, and circuitry interposed between the first and second set of connectors for delivering current from the battery to the ignition coil;
- and
- a scale operatively positioned relative to the circuit for indicating a strength of the ignition coil by measuring a gap across which a spark plug connected to the ignition coil produces a spark.
A tester for testing a vehicle ignition coil, the tester comprising:
- a support structure for supporting the ignition coil after it has been removed from its vehicle;
- a circuit coupled with the support structure and including:
- a first set of connectors for electrically connecting to a battery;
- a second set of connectors for electrically connecting to the ignition coil;
- a capacitor electrically connected between the first and second sets of connectors for storing energy from the battery and delivering a current of sufficient voltage to the ignition coil;
- a switch electrically connected between the first and second sets of connectors for delivering current from the battery to the capacitor and ignition coil when activated;
- a spark plug receiver for receiving and connecting a spark plug to the ignition coil;
- and
- a scale operatively positioned relative to the spark plug receiver for indicating a strength of the ignition coil by measuring a gap across which the spark plug produces a spark.

A tester for testing a vehicle ignition coil, the tester comprising:
- a base for supporting the ignition coil after it has been removed from its vehicle;
- a circuit coupled with the base and including:
- a first set of connectors for electrically connecting to a battery;
- a second set of connectors for electrically connecting to the ignition coil;
- a capacitor electrically connected between the first and second sets of connectors for storing energy from the battery and delivering a current of sufficient voltage to the ignition coil;
- a momentary switch electrically connected between the first and second sets of connectors for delivering current from the battery to the capacitor and ignition coil only when manually activated;
- and
- a grounding post;
- a spark plug receiver for receiving and connecting a spark plug to the ignition coil, the spark plug receiver being shiftable to support the spark plug at various distances from the grounding post;
- and
- a scale operatively positioned relative to the spark plug receiver for indicating a strength of the ignition coil by measuring a gap across which the spark plug produces a spark.
