1985 Mercury 115 6 cylinder sparks issues.

I have spark on 1,3,5 but not 2.4.6. I have swapped stator wires , trigger wires, and replaced the bottom switch box all with the same results.

Mercury recommends replacing both switchboxes, something about a biasing issue.

Did that both switch boxes are brand new. I jumped the tigger to from the top to the bottom with same results and did the same with the stator. I am at a lost with it

Your original post said "and replaced the bottom switch box "

Yea I bought two so just did the bottom one since the top one was working. After I posted I was reading that the top one could effect the bottom one so I replaced it but had negative results.

Thanks for the website had helpful pointers will try it out and let you know. It's looking like try the replacing the flywheel I spare engine for parts so will try it out. Might try the stator put I all ready swapped leads form top to bottom and still have the same problem.

Still no luck, swapped stators fly wheel and trigger and same result no spark on 1 3 and 5.

Did you disconnect the black/yellow wire at the switchboxes?

 

[JJ8191]

Yes still get the same results.

 

[JJ8191]

I just replaced the stator and trigger both are CDI products still have the same results. Bottom switch box not working.

Internal breaks in the wires/connectors

The top pack could have had the bia's problem and damaged the new pack you installed then the new damaged pack damaged remaining new pack..
