Saturday, A friend's Commando refused to start, I did the troubleshooting routine, found no spark, used the test switch on the Tri-Spark, rapid blue spark on both side. The red LED lights and goes out as the engine is rolled over, as expected. However, there is no spark when the engine is kicked over. Nothing. Old plugs, new plugs. several tests gave repeatability, NO spark. Is this the standard Tri-Spark soils the sheets failure mode?
