I have a lethal weapon 3 machine where the gun will not activate the plunger.

I push the start button and try to fire the ball but nothing happens.

Then when i hit the flippers the score starts to run up with each flipper hit, as if the machine thinks there is a ball in play.

I thought that the machine cant tell if the ball is there ready to be fired or has already fired. Maybe the launch lane switch that senses a ball is ready to be fired was bad. I put an reader on it and that switch is working.

The switch test shows that the shooter switch and launch lane switches are working.

When i run an active switch test it shows the switches for the 3 trough switches are active which makes sense... but it also shows "left 4 bank #2" is active. Should that switch be active?

What else can I check?

Dumb question, but did you confirm the coil isn't bad? Could be an issue in the switch matrix.

When I hit start and then start hitting the flippers, the ball will eventually fire, it also fires on startup... so I know it does work, just not triggered by the gun trigger being pulled.

Which coil would I check?

I have somewhat resolved this. One of the side targets was pushed down and making constant contact. Showed as "left 4 bank #2" in the active switch report.

Once I bent that back out to not make contact unless hit the gun now fires.

Does anyone know off hand what this coil is or what it can be replaced with.
