Hmm I’m getting 0.17 volts across the red & black wires @ IC1. Their source points on the PCB2 regulator board. P3 is disconnected from the control board PCB1, so there should be no load on it.

Maybe I need a new regulator?

I Never even noticed C4 hidden down there!

And that big clip-on capacitor C3 @1000 uF, can you still buy those?

*edit* hang on, I just realized those points depend on the state of C4, I do need to measure before & after the regulator. I don’t see the voltage listed before the regulator on the SM though.
