I have an old Dover elevator and no prints. Vertical Express can't find the prints even though I have a job number. The issue I have is, I've troubleshot the problem to a rectifier, (not getting proper voltage to a relay coil) but I can't identify the actual rectifier. I've attached a picture, any help is appreciated.

Thank you
Stephenie
