Okay folks. What is happening is the spark plug wire is back feeding juice into the wire. The controller can't handle the electricity and is physically jumping the button causing the jumping issue.
I work for TrailTech and have talked extensively with the engineer who designed this thing. We are experimenting some some clip on Ferrite things that go on the wire. They drop shipped me a giant bag of them. If you have a TTO that is doing this, please send me a message and I will mail you one.
You clip it onto the cable and it is supposed to absorb the rogue noise. I have passed this thread on to them, but this thing was designed a decade ago, not much hope of a retooling at this point even though it is a 30 second fix in the circuit layout.
