FIXED: Changed out leaf switch with a different one.
Game Plan - Sharpshooter

The "S-H-O-O-T-E-R" drop targets all work fine except for the first "O". The light displays during attract mode and during lamp test, however, upon dropping the target the lamp remains unlit, and the shot sound is not heard. Additionally, it will not register as being knocked down, thus my targets won't reset until the ball is drained.

The startup shows 6 flashing lights on the MPU, and the self test shows no codes.

The switch makes contact, and I have cleaned the contacts with a business card twice.

Recently I opened a set of wires that were soldered and taped, thinking perhaps there was a poor connection. I found that when close the switch and connect with bare wire or test leads to a wire further down the line of the target, the light works and the sound is made. I'll include some pics, hopefully the right spot.

So is this indicative of a bad switch, or not necessarily? The other wires connected to this target appear to be soldered well (again, hopefully the pics show up here).

I have also tested the diode, that checks out similar to all other diodes from drop targets.

I also have an "8000" bonus points light that is not lighting during any test or play, yet the bulb works. That may just be a socket, but thought I would mention it.

All others aspects (non physical) appear fine.

How else would I go about testing the switch, aside from pulling it from the play field underside?

Thanks for your suggestions.

I just checked again, doesn't matter if I touch the contact circle or not, that dog won't hunt. The other targets all fire when jumped with a wire, sometimes with the contact, other times just the leaf/blade itself.

OK, so how do I check continuity? Do I have to go into the schematics and follow the wire back to a board?

From what I can tell (and I'm new at all of this) I need to follow the Violet/White and Blue/Green wires back to J6 on LDU-2. So how do I actually check?

Also, if I'm correct, since when I jump from the leaf/blade to the Violet/White wire that is uncovered I get the lamp and noise, isn't my issue somewhere between there?

Changed the leaf switch out with a different one.
