I've recently started having issues with my gas pedal assembly that I'm running on Jason's Pi Position setup in my old PP cab.
I pulled the pedal assembly out to clean it up and reflow the pot since acceleration had been a little flaky. After reinstalling it, I got a low-voltage error when pressing the pedal. Then, in the test menu, I wasn't getting any pedal response at all.
When I pulled it back out, I noticed the middle ground tab was bent — possibly grounding itself against another lead (self-inflicted stupidity ).
To rule things out, I ordered a brand-new 5K pot from ArcadeFixIt and installed it. Unfortunately, I'm still not getting any pedal reading on either the PP1 or PP2 test screens, even though everything else is working fine.
Most of the troubleshooting threads I've found deal with acceleration issues while using the original PP PCB, so they didn't quite apply here since Jason's Pi Position cuts that board out of the equation. My gut says it's a power issue, but I'm not sure where to start looking.
