I'm a member of the volunteer Fire Department and we bought two of these M1078 2.5 ton trucks through the state about 10 years ago.
The ctis has never worked in either truck we just aired the tires up normally in the spring and fall when we use them.
Monday out of blue after a call, the dump valves on the frame rails opened up and dropped all 4 tires down to about 10 pounds then stopped.
The ctis valve under pass kick panel has had the electric connectors unhooked since we have had it and the controller has never had a light on it.
I made and installed this manual setup, works awesome except the right front tire still vents through the qd on the frame till it gets to about 50 pound then it stops. Other 3 tires stay up. Swaped diaphragm in the regulator on tire with known good part and still does it. Where is the leak? What can hold that regulator open on only that tire? Hub seal?
Can we plug up that wheel some how so I can get through fall fire season and fix it this winter?
Thanks

Manual CTIS Conversion for M-1078
After severals request to start a post on this topic, I'm going to give it a try. I purchased my M-1078 in December with the control box missing from the cab. After reading several posts on the CTIS, and learning there is a lot of people having trouble with them, I decided to go the manual...
