What can cause an intermittent spark?
Intermittent misfires are often caused by a weak spark or a lean fuel mixture. Loss of spark is caused by anything that prevents coil voltage from jumping the electrode gap at the end of the spark plug. This includes worn, fouled or damaged spark plugs, bad plug wires or a cracked distributor cap.
What causes no spark in coil and ignition system?
• A good coil and ignition system should produce a blue spark at the spark tester. • Typical causes of a no-spark (intermittent spark) condition include the following: 1. Weak ignition coil 2. Low or no voltage to the primary (positive) side of the coil 3. High resistance or open coil wire, or spark plug wire 4.

How is intermittent pilot ignition different from direct spark ignition?
The Intermittent Pilot uses a Spark Ignitor to ignite a pilot flame, that then in turn ignites the main burners. The Intermittent Pilot, unlike Direct Spark Ignition, uses gas.

What do you need to know about intermittent ignition?
It may be necessary to establish a good connection to ground by using a wire with a clamp onto the gas line or equipment chassis and connecting it to the ground terminal of the module. All connections should be clean, unpainted, and generally offer good metal-to-metal contact.
