I have a new to me 1998 Johnson 35 HP 3 Cylinder J35TKLECA with a No Spark Condition on all 3 cylinders. Ran one day and not the next. CDI and coils were replaced, it again ran one day and not the next. Bypassed the key start, same issue. CDI and coils were tested and are in spec. Previous owner stated that he had it looked and and was told it had a "grounding issue" and the tech had it running in 3 minutes. Tech is no longer available to ask what it was causing the "grounding issue". All grounds, including the battery terminals were cleaned to a polish, same issue. I have ran out of ideas, any input greatly appreciated!
