Need wiring diagram please for repair

I posted this in my other post but wanted to make sure everyone would see it. You might have what we need and we need it in order to move forward. My wife and are are moving from NY to ID and our bus is stuck in Virginia. This Bus was supposed to provide us with the way to move everything and was going to be our home while we built it into a skoolie to travel to our kids at the different military bases they are all stationed at.

Does anyone have the wiring diagram for a 3126B mated to MD3060 the Shop says they do not have the wiring diagram. Not sure if it is relevant but this is for a 2001 Thomas.

The shop says that they are not able to connect to the ECM. I have another thread going.

Tow the bus home, stop throwing money into their pockets! They either know how to troubleshoot or they can suck you dry while they learn on your dime!

Once your home, see if you can either borrow another ECM or take you ECM out and have it tested in another bus or send to a shop for testing.

I also posted in your other thread a video link. It covers a CAT - Crank but no start scenario.


ALSO... by utilizing the forum search button I found a thread that answer your question.

The OP did not say what bus he has other than a 2001 Thomas. I am not sure it is a Saf-T-Liner MPV or an FS-65. They are different animals.


Goldens, please fill out the bus specifics in your profile so we can help out with bus-specific information.

True that.... but the 3126 operation/starting is basically the same, bus/truck....

But specifics is always much better!

Thanks for the reply, I did see that post about the manuals and downloaded all of them. I am actually not sure how to find out exactly what bus i have I believe that it is a Thomas HD. I just submitted a request with Freightliner to get connected to the DTNA connect which on the website says is also connected to the EZWiring which can help with wiring issues. I will also call the local dealer and see if they can help. Too. As for towing the bus home I would but the bus is in King George Va and home is in Albany NY. Unless someone has a spot near there I can have the bus towed too while I work on it.

Not sure if your familiar with dean from the skoolie but he has the 3116 engine and in one of his YouTube vids he hits a bump and his engine shuts down similar no start scenario. Turns out it was a fuse under the dash, one of the big 50amp ones I believe. Also I have the same engine, my mechanic recommended me having extra timing sensors on board for this kind of thing. Cheap part and easy to swap out if you donít have air brakes. Good luck
