M818 to civilian trailer electrical plug problems. - Steel Soldiers::Military Vehicles Supersite

New member as of today. I just bought a M818 for pulling grain wagons and pulling a hopper bottom. The air lines hook up fine but the trailer plug is wrong. Is the M818 trailer plug putting out 24volts? Is there an off the shelf adapter or do I have to cut off the trailer end of the wire and put on a civilian trailer plug? Thanks

The 818 has a 24 volt system. No adapters that I'm aware of. Instead of cutting off the cable you could get the female end off another vehicle and adapte from there. Your trailers will need 24 volt bulbs also (avaliable at napa).

I have a uncle with a pintle hitch tag trailer and thought it would be nice to use but the electrical issue is a problem. and i hate to put 24v bulbs in it as his trailer is 12v

There was a thread some time back that had a link to a off the shelf adapter for doing just this. You just plug the military plug in one end and a civi plug was on the other end.

be careful pulling that grain trailer. you will most likly be overweight for the 818 on the highway.

Thanks for all the input and answers. I have a stong electrical background and with your tips I think I will get the lights on. As for overweight we are lucky enough to farm within a 2 mile raduis and we dont need to travel any major roads. Todays project was to remove the military pintle and figure out how to adapt a cusion clevis type swivel hitch to the M818 so we can also pull center dump grain wagons when not pulling a trailer.

If John Deere made a specialized grain hauling truck for this purpose it would cost $150,000.00 and not be one bit heavier duty or better built than this truck!!
