MEP 803a main terminal no power I was just out working on this MEP 803a.There is a relay, about 4.5 inches square between the power selector switch and the main terminals. 3 large power wires in and 3 large wires out directly across. There are 3 smaller wires on the large input wires and another 3 small wires on the side. I find no part number or identifying marks. I removed the cover and found 3 terminals that made connection when I tapped it with a wood hammer handle. Can anyone identify this part? Name or part number is preferred. Can anyone tell me if there is another reason this is not working? Perhaps some other module not giving a signal to power on?
