CAUTION: Ensure negative battery cable is disconnected prior to removing Black and Blue wires from coil. DO NOT disconnect Brown wire from coil. Ensure ohmmeter leads are installed with (+) lead to ground and () lead to Black wire.
Install ohmmeter between Black wire and ground. See Fig 2 . Place ignitor checker SW1 switch to the T1 position. Hold ignitor checker SW2 switch on and note ohmmeter reading. Ohmmeter needle should rise to 1/3 the distance of the scale and then return. Replace ignitor if needle operation was incorrect.
Turn ignition off. Disconnect ohmmeter and reconnect (+) lead to ground and () lead to Blue wire.
CAUTION: Ensure ohmmeter is installed with (+) lead to ground and () lead to Blue wire. DO NOT reverse leads or damage may result.
Turn ignition on. Place ignitor checker SW1 switch to the T2 position. Hold ignitor checker SW2 switch on and note ohmmeter reading. Ohmmeter needle should rise to 1/3 the distance of the scale and then return. Replace ignitor if needle operation was incorrect.
