Magnum Chassis Service Manual

Hi, new member here, I am trying to see if anyone has access to a service manual for a 2001 Monaco Riata, also known as a Harney coach built by the SMC corp. It s built on a Magnum chassis. I am currently trouble shooting a exhaust brake issue and need wiring schematics for the transmission and ABS if possible. Any help would be greatly appreciated!

I have the wiring schematics for the Harney coach. Mine is a 2000 classic Sedona. I can send you the wiring diagrams or you can go to SafariaDiesel Groups .com and probably find all the info you need.
Let me know if I can help. What problems are you having?

I am working on the exhaust brake function which is not getting power to the pac brake. I have the signal coming out of the TCM but lose it going to relays from the ECM and ABS. I am specifically looking for wiring diagrams for the ECM TCM and ABS to see how this circuit is wired, so that I can redo it if need be. I have all the original owners manuals but no wiring schematics are in it. Thanks again!

I don't have any wiring diagrams specifically for a Harney, but I have a collection of wiring diagrams for early SMC-Beaver (Magnum chassis) coaches. I would suspect they are the same or very close.

Go to the link in my signature line, then open the folder for "1984-1999 SMC - Beaver-Monaco-HR". I would start with the drawings for "1999 Patriot Exhaust Brake wiring diagram".

Good luck
