My big guns' right canon always misfires. It releases the ball early, triggering a false 2 ball multiball. sometimes it happens from a launch of the ball out of the shooter lane, sometimes from something else on the playfield. I originally thought it was due to a vibration causing a switch closure or similar, but cant see what triggers the canon release firing. Always the right canon misfiring, never the left. No switch errors.
Any assistance is appreciated. thanks
