Joe, I have a 2500 Duramax/Allison and had the problem with my trailer brakes suddenly quit working. There are four pages of my troubleshooting on the "Diesel Place." You may want to read them. I did use the "headlamp test," and it does work.
The one thing it will tell you is whether your problem is with the trailer or with the truck. I bought the headlamp from a wrecking yard and made up the "tester" myself.
Here is a link which I hope will work:

There a lot of "dead ends" and false starts on this thread, but it did turn out to be helpful. The poster "HeyMcCall" was the one who was on target about this tester. Note his responses.
