So I took delivery of a M931A2 today. It came from Fontana, and at pick up my trucker guy Robert mentioned that the air dryer was gone and that he had to bypass it to get it up on the trailer. Anyways so its gone. I took a quick look at where it was originally installed and it seems that it had one electrical plug and three air lines going to it. Right now he just hooked up the two larger air lines together to get it to hold air. My question is should I start looking for an original replacement or are air dryers pretty much universal? I guess it would have to be 24 volt though. I do know they are an add on to these trucks for convenience of not having to drain the tanks daily, but they seem to make sense to have. I really don't know much about how these suckers work or what the electrical wire is for.
