Problem- Help identify missing electrical component

[Shanghyd]

I'm having some issues with my bridgeport. In another thread I'm trying to work out a servo problem. During the process I found a space where it appears a part was installed at the factory.
Next to the space is a diode that only has one wire going to it. Wire number 113.
Anyone know what is missing/ The wiring diagram in my other thread shows this area.

the answer is '5'



how about telling us what machine it is, preferably in the title so the right people will read it.

The part with the one wire appears to be a bridge rectifier (REC). It should have a pair of AC supply wires, usually on opposite sides(corner to corner) and two DC feed to a regulator (REG). This will supply the 24 volts DC to the machine. Note: If you have a 24 volt DC power supply somewhere else,(non-factory) this may not be needed.

Looks like a very old interact machine with a Heidenhain control.
That is a bridge rectifier. Just to the right is a "bread-boarded" voltage regulator. Later they more sophisticated and had a nice enclosed 24VDC power supply.
