So my Kohler CH18S had a coil problem. One coil tested out bad. So I replaced both coils while I have things apart, ... and now I have a coil grounding issue.
When the kill wire is connect to both coils, the engine will not start.
If I remove both kill wires the engine will start, and will consequently stop when I reconnect the wires.
If I remove one kill wire from either coil, the engine will start and run on one cylinder, until I reconnect the second kill wire and then the engine stops.
If I disconnect the kill wire going to the wire harness, it makes no difference to the above.
It appears that the kill wire connected in series from one coil to the other coil is grounding out from coil to coil.
I have no idea why this might be. Unless I simply got the wrong coils.
So I thought I would ask advice before I go rewiring myself a separate kill switch while I have everything opened up. Or I guess I could fall back to just choking it to turn off. Hmm....
