    Should be pretty easy to trace out. Just take it out and start drawing.

    There is a simple 'logic' relay (black rectangle) and two micro-switches and a cam that control the opening and closing movement. I my case, the shutter jammed (enlarger was in a community darkroom) and probably someone shut it down when the resistor blew (fortunately like a fuse protecting the motor) and gave off a lot of smoke.

    Subsequently they sold it to me. The repair was easy: unjam the shutter and replace the burned resistor.

    In your case...could be any one of a hundred occult things based on the (normal looking) picture.

    Yeah. It seems like the 1000 watt head is quite different from the 2000 watt. Until I can find a diagram for my set up , I’m not sure even how it works 100%. The EST 1000N power unit has a plug on the back that I’m not even sure if it has to be used or not. Tempted to just sell it.
