    Anyone with a 400 SMT willing to take a picture for me?

    Trying to fix up a 400 SMT I bought with some other equipment. Talking with Arcon they suggested replacing main caps and one of the SCR pucks. Did that, still no output even though the main board is firing a signal at the SCR's. Someone had been in this machine before I was so I'm wondering if they didn't misplace a wire, I need a picture of where the wires connect to the top of the bolts holding the "main SCR assembly" to the white plastic frame, and another picture of where the SCR wires connect to the bottom of the main board.

    Thanks!

    Any chance you can read the value off of c8? It seems to have lost the magic smoke. Possibly from having 110 run through the contactor circuit?

    Can you take a top view of the studs so I can see which color wires attach where?

    I'll get you a pic of that board shortly

    Sorry I meant studs on top of the white plastic - where the main SCR assembly (the big heatsink with two SCR pucks wedged in between) bolts to the underside of the white frame. There's a red and yellow wire going to them

    One side says "104" the other says "K5M" for the cap in question.
