  1. Thanks for your reply. I have two pictures I have attached. I plan to sketch a circuit diagram this week which I will post. The Aluminum heatsink is not taken to earth but a wire from the block it bolts onto goes to two other points in the system. regards. Jack
  2. Varo R153 Rectifier? (7803 - wk 3 1978?) Hi There, I wonder if anyone could please help me identify the above component (and a possible source)? It is part of a Woods Ultracon U-100 Motor scr cotroller and is the first component across line and neutral (240VAC) after the switch. The device is press fitted into a heatsink and has 3 blade terminals on an insulated post. Line and neutral are across two (with a dead short between them - hence the reason it is tripping the 16amp CB.) The third terminal goes to F2 (Motor field coil) and another point in the unit. Using a multimeter, there is a diode drop from the third terminal to line and also to neutral. A datasheet would be perfect but any information would be appreciated. best regards JAck
