135 Evinrude has no spark

[imokintex]

I have a 1974 135 Evinrude V 4 with no spark on any plugs. I took the sensor wire off of the power pack and grounded the sensor terminal of the pwer pack while cranking and got a spark. Does this mean that the timer base assembly is bad. Seems to me if you ground the sensor and the power pack fires the coil that the Power pack is good. Any suggestions as to which one is bad?

There are four sensor wires on the 1974 V4 135HP powepack, so it is difficult to understand your testing method.

CDI has step by step troubleshooting for the powerpack if you don't have a service manual: http://cdielectronics.com/InstallSheet/113-1731.pdf

I took the # 9 wire off of the power pack and took a wire and touched the number 9 terminal and then tapped the other end to a ground while cranking and the number 1 coil fired

I'm confused. I think you should follow Ezekes advice above concerning CDI.
