Help! we have a 2001 bluebird with a cummins engine and allison trans. I took the heaters out and i guess I didn't do it right. The bus now won't start and the check trans light is on. I drew out what I did you can see it here hester.jpg . If that link doesn't work see it here: https://www.mosaicifs.com/hidden.html

as far wiring goes, there were 2 clusters of colored wires (1 for each heater) that connected to the panel at the front side of the bus. there was also a gray cable that went from that front panel to the back where it had a ground (connected to the wall of the bus) and continued on to the heat pump under the bus (I think). that part had the brand name "bergstrom" which google said is a bus heater. anyway, thoughts would be helpful!
 
Take a look at the TCM fuse to see if it has blown.

Go to the bluebird website and see if you can download the wiring diagram for your bus.


Don't disconnect any more wires until you understand how your bus is built.
 
Well, I just deleted my heaters and noticed the same gray wire, I didn't touch mine. I can mess with it and report back if it is indeed the wire.

Cut'em all off and my bus started okay. I would look at the fuse as suggested. 2005 Blue Bird A3RE so our setup should be very similar
