the pot is not turning on the PSR-25, there are 3 leads on the potentiometer I ran the 2 outside to the psr and the middle one to earth ground ... is that wrong? I see what looks like maybe the middle and 1 outside jump together? I didnt really see any pots with 3 leads like mine

you need to use the center lug, and either of the outside lugs. which one you choose will deterimine if you ramp power up by turning clockwise or counter clockwise. cut the un used lug off. dont ground it.

Here's the one I built ,It was very difficult to fit this in all in a 4x4x2 box since my amp gauge was so big . I had to put the pot on the back it would not fit below the gauge ... I added cabinet handle's to protect the dials

Wow these run nice , you can set on exactly how many amps and correlate that to exact temp. thanks all
