I just bought a Flash Gordon and am working out the bugs. If I hit the stationary target (see pic)the game tilts.

Don't see it shorting out on anything. Kind of crazy.

Any thoughts....

Switch matrix error. Switch wired wrong, diode on backwards, a short to switch wiring or switch lugs. Causes a switch hit to register as something else.

LTG : )

Game has a switch matrix... so start with that usual troubleshooting. Looking at diodes and make sure the switches aren't grounding out to something nearby.

Looks like that target may be in the same row as tilt. Check diodes and the capacitor on that switch

Looking over this switch here's a picture of how it is wired.

I don't know if someone can verify that that's wired correctly or not or post a picture of a properly wired one that'd be great

Could also be a bad cap on the switch's.
I had similar problem on a bally game that ended up being that one of the
coin switches was stuck closed, game would play, soon as I hit certain switches (targets), game would go tilt.

Cut one leg off the yellow cap on that switch, and the cap on the tilt bob/roll tilt in the cabinet and see if it still tilts when that target is hit.

This is going to sound weird but when I was messing with the switch if I held onto it right where the brown wires are soldered into the switch with my thumb and index finger I could sometimes get the switch to work okay but I would have to push the switch far enough to where it's grounded out on the mounting bracket for it to work.

I will check out the other suggestions that are mentioned to and report back.

Capacitor and diode that are on there now I installed so I know they're new

Looks like you are pointing to the upper target and not the lower? The lower right target could cause tilting.
Make sure you do not have a stuck coin switch on the door.

it doesn't take much to pop the driver chips in those things....i sed to replace all four and put in sockets to make it easier to troubleshoot them down the road....

Well I got that switch working.

I cut off both the diode and capacitor off and soldered a new capacitor where diode was and it started working.

Thanks for the help it's greatly appreciated.

Sometimes new parts are bad, too. I just spent some time chasing down a switch problem on a Bally Frontier to find out the new switch capacitor was the issue, and then a different switch had the same problem. I am going to order a new batch of capacitors, install them, and throw the other ones away. Makes me wish I hadn't replaced the original switch caps in the first place.
