I'm on my last issue with my Jet Spin. If I hit the left roto-target switch it will score 100 points less that what is showing on the target but the center and right targets score correctly every time. So if it shows 200 it will score 100 only strange issue is if 100 is showing it will score 500 points. The switch on the playfield that scores the same points as the roto-target is doing the same thing so I don’t think it is the switches on the roto target itself. Below is the schematic section I believe is involved.
Thanks,
Joe

It ended up being a missing wire on the roto-target wheel itself replaced the wire and all is good now. Thanks for making me double check the wheel itself!
