    Default NSN: 4120-01-327-5447 power plug help

    Hello,
    I saw one of the AC/heaters on Colmans. It caught my eye and I am interested in getting one. However it does not come with a power cord. All the searches I have done do not turn up any solid results. I know the plug at the AC unit is a little different but at the other end does it plug into a standard 110v outlet? Is there a place I can buy one or does someone have a place they can point me to get the parts and how to wire the plug up correctly?
    Thanks..

    Called Colemans yesterday and today. They are going to do some research into a plug. Seems strange to sell the unit but not the power cord.
    My own Google search has turned up nothing. Hoping a solution will turn up.

    Looks like the manual for that unit is TM 9-4120-403-14. You might try finding a copy of that and see what it tells you.

    Surplus stuff like a/c units are often sold at auction without things like power chords (in fact, getting the chords would be a pleasant surprise!), Colemans likely didn't get any when they bought their lot(s).

    If they can give you the code off the plug on the unit, or you can figure it out from the manual, you can probably find a matching bendix connector and make a chord.

    Cheers

    Do you have the two TM's for the air con? If so, say something.

    Edit: To late. I already uploaded them, so look in the TM upload section, or Aux Equipment.

    No, the plug is normally a pig tail, that hooks up to a gen set output load terminals. It has a canon plug on the end that fits the Air Con.

    Thanks for the manuals. I will read through them tonight. I'm hoping there's something in there that'll tell me what type of plug it is and how to wire it up. There is another post that I found that does list the part number for the plug but I am unsuccessful in finding a supplier. What concerns me is that according to what I read or I've heard the plug has four pins. Just makes me wonder how the AC system with 3 wires hooks up to a 4 pin plug.

    Don't ask me why but my kid wants to go to Pennsylvania for spring break. We'll be traveling past colemans and I'm tempted to buy one although I won't have a plug ready by that time. Tossing around in my mind whether it's worth just buying one or just waiting until I have all the info.

    I saw that 4-prong plug. Interesting. The a/c units I have for the shelters all have 3-prongs.

    Cheers

    Can you recommend a shelter AC/heater that would be better for me? Still like this model very much but I'm no electrician. I don't need to burn the unit up my 1st attempt .

    Can you call Coleman and ask what J number is next to the power cable jack? Also, if you think you have the part number for the plug, list it here. We can look it up and see who the supplier was for the army. Most, not all, most air con was three phase. As this one is 115 VAC, don't assume that it should have just three pins/wires. The milatary tends to use the same plug on many things. Having a plug with one pin not used is nothing new. It saves money in the end. And you have one less part to worry about in your inventory.

    I went back to the original post that had some information on the plug. They say it is a Amphenol Female Military Mil Spec Circular Connector MS3108A20-4S 4 Pins 90 Deg ".
    Did some looking and didn't turn up much.
