Connect the ignitor, lamp, and battery as shown in Fig 1. Using a dry cell battery or continuity tester, apply voltage to the signal input terminal of the ignitor unit. Lamp should light when voltage is applied, and go out when voltage is removed. If not, ignitor is bad.
Use low-voltage dry cell battery or ohmmeter.
NOTE:
This test can only determine when ignitor is bad. Even if ignitor tests out as good, it could still be defective.
