Protective Control Box M923 PCB Interchangeable models?

[indyradar]

I have a 84 M923 5 ton. I blew the PCB. I got another one and the numbers on it are different. Plug is the same. There is NO NSN on this one (new) but the part # is different this one (NEW) is WSU-4001UT OLD ONE was WSU-401OUT are they interchangeable?

I dont know, but a quick google search finds this. I'd call him and find out. http://www.eriksmilitarysurplus.com/prcoboxform8.html

I don't believe that is the correct one. From Erik's it is a M809 box and those will not work on a M939.

The opposite is true that a M939 box will work on the M809.

No. Some member have had a little luck repairing them.
