This is a must have for CDI ignition systems in outboards, snowmobiles and motorcycles. I spent hours letting a 1995 60 hp Johnson outboard drive me crazy with intermittent ignition problems. I bought this tool, hooked it up to my multimeter, and determined the problem was the timer base. It took me an hour or so to figure this out - and I've been fighting this motor for a month! I could probably conduct the tests now in about 30 minutes. I bought the part, installed it, and the engine fired right up! I'm heading in for a celebratory cold beer right now. Quite procrastinating and buy this tool!
