Help, I replaced the powerhead on a 1994 Yamaha 70TLRS with a new Yamaha Factory unit. At first start it ran for a min then died, this happened multiple times, As time went on it would run for shorter amounts of time. now i have no spark I am leaning twards a bad CDi Powerpack on the crank sensor circuit. I bought the Yamaha factory service manual and all cdi unit ohms were in speck except the crank circuit. it showed the following readings in the pic using a new analog Volt Meter. I also tried disconnecting the yellow Emergancy Operation Wire thinking that that would make it run on preset values instead of depending on the sensors - but that did not help.
Just cant see how it ran before and now dont. I have triple checked wiring and grounds, kill circuit.....
If I need a PowerPack any suggestions where I might find a good used one?
other info:
When i replaced the powerhead i removed the oil tank & oil pump drive then blocked off the oil line hoses to run straight 50:1 mixed gas as the old powerhead failed on #1 cyl due to lack of oil. after mixing the oil & gas i emptied the carbs then disconnected the fuel line and pumped a couple quarts of fuel mix to be sure all was good, then reconnected the fuel line
