Hey all, I have a Galaga mini with joystick issues. It will not move the ship to the right...at all. I have already taken the stick assembly apart, made sure all points are hitting right and that the lil pads are slightly sanded to get off any rust or what not. All the solder looks good and in tact, same with wiring. Ive already been in contact with a guy here and these sticks (original) seem to be hard to find. Id love to keep the original... so what to check/do now??

Should I go through and re-solder all?
Any other suggestions folks? Thanks in advance.

It could be a broken wire, but troubleshooting is the same no matter what. Pull the CP off and use a multimeter to check continuity at the joy itself to make sure it's closing properly in both directions; check from ground to left, then ground to right. Then test continuity between the quick release for the move right line that plugs into the joy to the end of the control panel harness molex. Then from that molex's mate to the PCB edge connector, and from the edge connector to the pin on the PCB it goes to.

That'll isolate your problem to the joy, the CP harness wiring, the main harness wiring, or the edge connector.

I haven't rebuilt any of these, but the leaf switches in there don't look too exotic. Bob Roberts sells repro leaf switches for a few bucks. It should be trivial to replace them, if that is indeed the problem.
 
I would just swap the wire on the joystick from the working side to the non-working side and test it out again. If it works on the opposite side, then you know it is the leaf-spring/contact. If it doesn't, then you know it is the wiring. Or you could use a multimeter too, of course. :)

I've also been told that you are only supposed to clean leaf-spring contact points with something like cardboard or a business card, not sandpaper. Otherwise you run the risk of removing the contact material coating, and then it corrodes faster.
