Unless you have an extra grand lying around for a new ignition module. First, as Roger noted, it's almost impossible to see. Second, a $10 tool, an Ignition Spark Tester replaces the weak spark with a bright light that makes the test safe and easy to do. Ignition Spark Testers are available from sources as varied as Harbor Freight and Snap On.

If it is done wrong you can cause damage. I never look for spark and have such a tool to check wire/plug continuity. -------- Roger Lee Tucson, Az.
