Check the switch matrix ?
I had an issue with it firing from left flipper I kept playing to establish the switches involved and found that it only happened with ball locked.
In switch test, I then popped balls in the locks and hit the flipper- sure enough, phantom switch for the yagov kicker. I then followed the system11 repair guide on switch matrix to fix it.
Once you can reproduce it, you are halfway there as you can test connections, diodes etc, replace and retest.

Not so much a test as a troubleshooting process. It helps narrow down the number of places you need to test. It takes a bit of learning but I found this good :

I printed the switch matrix chart and then determined which switches were involved in the phantom kicker switch. This then left me with the various parts of the matrix that I needed to check (confirm diodes ok, check solder joints etc)
