1988 Johnson 110 hp no spark, looking for ignition wiring diagrams, debug steps

[akoz]

Hi, I have the "oddball" J110TLCCA outboard that has only 1 powerpack feeding 4 coils and my Seloc manual only covers the 2 powerpack version. I'd like to find a wiring diagram and also the debug procedure for the ignition system. I just picked up this motor for $100, pretty much left for dead, but now it looks worth fixing as it turns over and has good compression. At this point there is no spark on any cylinders and I don't want to start replacing ignition parts without following the debug steps and the Seloc does not cover this. Thanks, Al

Maybe I missed something, but the links were for much older outboards. Thanks, Al

This is a good start, thanks. If anyone else can point me to a complete wiring diagram with the wire color codes, then that would be much appreciated. Thanks again, Al

Have you tried bypassing the kill switch circuit?
Unplug the single wire connector shown in the picture. The second picture shows the powerpack that this wire goes into. Under the insulator the wire is black / yellow
If you get spark after the disconnect the problem is in your key switch or the lanyard safety switch.

yes, that was part of the problem, now there's basically a bad coil, but spark now on the others.
Thank you!
