K2636 help troubleshoot

I’ve assembled a k2636. Manual is labeled H2636IP-2004-ED1 (rev. 3). Checked components, diode orientation, solder connections etc. Wired per manual page 8 (110 VAC, 60 Hz).

  1. when I apply power, the power LED comes on (load present or not).
  2. Both fuses are OK
  3. 110 VAC appears across load terminals (no load connected), but voltage does not change with any combination of potentiometer positions.
  4. When I add a load (tried 60 w incandescent light bulb), voltage across load terminals goes to 0, light bulb does not light at any combination of potentiometer positions.
  5. VDC across potentiometer does change with potentiometer position (both potentiometers).

Any thoughts on trouble shooting?

I’m very experienced, assembled quite a few kits.

Thanks,

Can you supply links to SHARP and HI-RES pics of your assembly, both solder and component side, so that we can take a look?

Please let me know if these are clear enough.

Thanks,

Sorry, the links don’t seem to work…
