My perc reverse button suddenly has stopped working on my Primary 04 RMK. I changed out the stator and it does not work on either the newer or old stator. I have 3 difference left handle perc reverse assemblies and they all seem to work on my backup 04 RMK, but none work on my primary 04 RMK. So it is not the perc reverse handle assembly. I have 3 different CDI boxes that I plugged in and that does not seem to make any difference either. I am running out of ideas for swapping components to find defective ones. Does anybody have any ideas for what else to look at? When I say it does not work, I mean the engine does not stop and restart going backward.
