Where did you add the GI lamp, this could be affecting the optos.
Nice to hear from you Dave. The GI is mounted underneath where the ball enters the playfield. That small ramp where you release the plunger and get the skill shot.
Nah,thought you mounted it near the trunk.
If the trunk is registering random hits then I would be looking at the eddy sensor......it may be a bit flakey. Easy way to test is in switch edges mode and observe. Bang the cab and playfield with your hand and see if it registers a hit.
