I have a 1987 Yamaha warrior that I replaced the stator in. The stator is new but I believe it is for a 1988-89 because the gray wire that is suppose to be in the 4 pin plug is connected to the yellow wire. My problem is it starts fine but cannot shut it off with the kill switch or the key. Have to pull off the plug wire. Is this caused by the grey wire? Should I cut the grey wire off of the yellow wire and wire the grey one into the 4pin plug? Thanks. Any input would be greatly appreciated.
