EDIT: This info is for a stuck button, not a rapid fire button! Check the bottom of this post.
There’s no way to disconnect the turbo switches, so scratch that. Closest you could do is remove the slider pieces so it always thinks the switches are down, but that’s not your problem.
You are gonna have to crack it open though. Somehow, the two wires for the R2 button are electrically connected. I figure there are three things you want to check, all require opening it up.
- Make sure the QD’s on the button arent touching. If for some damn reason the QDs on that button got bent and are touching, this would cause this. If they look like they’re touching, bend them so they arent and test it out.
- Microswitch in the button is dead or jammed. Pull off the two disconnects from the button, and wrap them lightly in electrical tape so they dont touch nothing else, especially each other! Plug the HRAP2 in, push the slider switch for the R2 button to half way (‘Turbo when pressed’) and see if it thinks R2 is repeatedly pressed. If it is showing as pressed, go to #3. If not, the problem is the button and can be replaced easily; just laugh and tell yourself the sanwa button mod you wanted to do is coming a little earlier. While you’re waiting, you can remove and disassemble that one button. If you spilled Coke on it and it got sticky, you could clean it and have a working button till the sanwas get in.
- Button short on the PCB. You may want to get ahold of Hori and see if they’ll swap you out unless you’re comfortable with a soldering iron. Even then, it’d prolly be easiest. If you’re gdlk with an iron, check for shorts on the PCB itself near where the two wires for that button plug in.
Oh, shit. Rapid firing the button? That’s different. Somethings not right with the turbo switches then. Take it apart and look for something shorting those two points on the turbo slider switch.
