I have the neon type and the spark gap type testers but both have draw backs. If it is sunny or you just can not see it from the handle or seat you are out of luck. You have to ask someone to watch while you pull the rope or turn the key. I am looking for a spark tester that makes noise of some kind. When there is a spark I want to "hear" it. Some type of buzzer or sometthing that will sound when there is spark. Does anyone know if there is such a thing?
