I did some NSN searching on Google and came up with a good supplier hit for the 939 control box, I purchased one for my 936A2 wrecker and it works flawlessly so far... I can't test the voltage regulator yet since I haven't gotten it started.

Southern Automotive Wholesalers Inc

I talked to Tom Tyson (tom@southernautomotive.com) and ordered the box from them (NSN: 6110-01-444-2546) brand new for $149.55 plus shipping.

They also make most of the rotary switches for that truck as well.

The only thing I noticed about the box is that it's completely sealed, no pipe plug like the older ones. Other than that, it hooked right up and for the first time since I bought it, the battery and run switches do something...

Later,
Joe

Fantastic. Good sleuthing Joe. Thanks a bunch. I think I will buy one for a spare for my 925A2.

No. They are different.

Mark, how are they different? According to the wiring diagram, the pinout is the same for both, except "E" on the 939 series first goes through a Neutral Safety switch before it gets to the ignition switch (wire number 499-498 instead of #14 for the m809 series. ..

Joe, how is the connector sealed, rubber gasket?

I don't know the truth of this...but this is what John Winslow told me. The control box on an M939A2 will work on an M809, but not the reverse. I never tried it so I am not sure. This is definitely what I heard from John.

I will have to look again as I didn't look that closely into it, but I believe you are correct, it's a standard cannon plug with a rubber gasket between the body and plug shell.

Gentlemen,

The 939 series box will indeed work on an 809 series. I can tell you from experience. I bought one a fewyears ago for my M813 and it works flawlessly. Just plug it right up. As said before, a 809 series box will NOT work for a 939 series.

Anybody got a junked one? Need a mate for the connector pictured below.
Chris, do you still have your old one?
Thanks.
