Hi guys
My name is Paul, I am new here. I have been around on the Mog mail list for a few years now and they recommended this place for great info.
I recently bought a US aArmy M 103 A3 trailer. It has a 12 pin NATO plug. My French 404 also has the 12 pin plug. So far so good.
When I first got it I noticed that the male(trailer) end of the plug is
keyed, the female(truck) end is also keyed. The two will only mate one way.
The holes in the female end were slightly misalinged so that the two could
not mate. I took the truck end apart and slightly rotated the plug in the
housing so that the pins and holes now line up. Both plugs have each pin and
hole identified with a letter. I made sure that the pins and holes were
correctly lined up so the letters match. Upon turning on the lights this is
what I found. Truck lights all work as before. Trailer lights: running
lights work. no brake lights, turn signals when activated do very strange
things. Pretty much everything blinks.
The trailer lights have 4 bulbs. Some of them are for blackout operations.
There are three small bulbs and one full size automotive type bulb with twin
elements. All the bulbs have MIL designations , and no Volt or Watt info,
although I know the trailer is 24V.
I am confused as to why if both vehicles have "standard Nato" plugs, the
systems are not properly communicating.
Should I identify each hole in the truck plug first and then do the same for
the trailer and switch the pins around? Or am I missing something?
Thanks
Paul
