Re: No Spark 1974 Johnson 85

I think you are talking about the power pack, it controls the firing of the coils. There are check out procedures in the factory manual if you have it. If not, go to the CDI website and locate the troubleshooting section for your engine and use it to help you find your problem.

i believe its the power pack when i switch the coils around they will fire and i took off my key switch and still same problem so i just ordered a new power pack.. so much for the lake tomorrow lol.. also on my Slater it looks like grease or something oozing out of it.. any ideas

Re: No Spark 1974 Johnson 85

If you have black stuff oozing out of you stator, it's gone or on it's way out. I think you can use an ohm meter to check it out. Look on the CDI website and see if they list the specs for it.

it's not black. its like a honey color.

Re: No Spark 1974 Johnson 85

No mater the color, the stator should not be leaking anything.

X2, if power pack does not fix problem probably bad stator. On a motor of that vintage a new power pack is a good investment.
