i have a six gun saloon game and when i bought the gun it had a standard Happ gun. the thing was broken and looked terrible so i found a revolver shell and adapted it to work. i took the laser and trigger switch out of the happ gun and made it fit in the revolver shell, using hot glue to secure the laser inside. i put it back together and it worked but the aiming was off. the red dot that it produced was too low for the sights. i took it back apart and glued it back in the correct position and now it is dead on, however it starts to walk to the left after each trigger pull finally ending up about 6 inches off. when you start the game over it is centered and does it again... what could cause this
 
I was thinking since you glued it down maybe heat would be causing it to wonder off.
but from what I read from your post the drift goes away when the game restart. Which might indicate something on your PCB is causing it to drift.
 
it didnt do it before i took the gun back apart. when you play a second game the gun centers back up and then drifts to the left again. i dont think the laser gets hot enough to melt that much hot glue
 
Bring home a laser sight from your Black Hawk and use that on the game, should work fine :).

I would say there is a resistance problem but the last time I tried to help you, you just bought another game....
 
I didn't buy another game, I bought the part that you said was the amplifier?

Ohhh, how did it work for you and how did you test the part to make sure it was bad?

I don't know so I just ask. I think the part I looked up was a transistor but enough clowning around, the problem at hand;

The gun drifts to the left but when you start a new game it is tracking fine then slowly moves/drifts to the left.

This sounds like a calibration issue to me and there should be some way to compensate for that in the manual. If not then there is probably a dogie pot or a bad connection to the gun. What happens if you leave the game on for about 1/2 hour or so then try it? The problem will get worse I suspect and maybe not track at all.

Also try to just 'track the gun' and not use the trigger AT ALL and see if the gun tracks fine or not.

The problem here is what is causing the gun to become misaligned then track that down. If the trigger is doing this there could be a high voltage drop that it is changing some other values.
 
I didn't replace the amp yet, maybe today. As for the gun, I will try leaving it on for a while. Need to look at it more.

some use a pot and as you move the gun to the right or left it will change the resistance but I don't think that is the setup you have as that is usually for stationary guns that are mounted directly to the cab.
