Brach, thank you again for the great troubleshooting advice. I was able to test the pedal today. Here’s what I found…
-Center pin of rate pot to pin 24 on IC is a good connection (metering at the IC itself)
-Rate pot has good 5V (4.98 to be exact) current on right (based on bottom view) lug
-Rate pot has solid ground on left lug
-Center lug of rate pot is metering 4.98V regardless of the position of the wiper (unless you turn it all the way counterclockwise and then it meters 0V)
Basically, the rate pot passes 0V when fully counterclockwise. As you turn it slightly clockwise, it jumps to 5V and stay there for the rest of the wipe.
It sounds to me like I may have a defective pot but I’d like to hear you’re opinion.
