Today I went (as promised) to a friends place to see if I could get his wallbox working again and spent much time with some success, the previously rebuilt TSR1 and stepper is working now but seems to pick up all numbers in a particular letter group. For example selecting L4 will play all L selections. It also trips immediately when a selection is made. It was getting late in the afternoon and I couldn’t figure it out so left it until I could get some advice. So here I am, What would cause this issue? Thank you, Mauro
