I punched your part number into parttarget. Confirm NSN is in the TMs for that machine....

Yep saw that in oshkosh. Im hoping someone has a parts donor around.

This part was only used by the military. No hope to find a new one, other then someone who bought up spare parts.

Did you test the bad one? Unhooked the wires and test?

Oh, yeah. Fits a MEP-004A also.

Per the Part Target link, appears to also have (2) other part numbers. Might this be it: https://www.4starelectronics.com/part_detail/E892CTP.html?

The part was missing.

Now you know why! Look in the bottom of the set, and the OVM box if its still in the set.

I believe that it is just a repurposed bridge rectifier (I say repurposed because that component is designed to turn ac to dc, and it is being used as a set of blocking diodes)

 

[Guyfang]

That's all it is.

A competent electrician should have no problem fabing up something. I am by no means a competent electrician. But think I could come up with something to fit the bill in a short. Make one.

 

[Scoobyshep]

In that case its an easy hook up.

Simple, just buy a bridge rectifier rated at 400 PRV and use 3 out of 4 of its terminals. Use the + and the two AC input terminals. Plus terminal to L2 and two AC terminals to the other inputs.

All good options.

I agree with "kloppk".. Over the last 30 years I have (tried) to restore many generators, radios, etc. IMO this is just a common bridge rectifier. For a few more cents you can by one rated for 1000 volts instead of 400 volts. This is just a little more safety factor. From the circuit diagram it does not look like you need one with a large amp rating but a large (25 amp) rating won't matter. These diode bridges can bought for around $5. Good Luck!
