Hello to all...
I have a 1997 Thomas Pusher with 8.3 Cummins and Allison 6 speed.
I drove this thing home in MAy 380 Miles without a Single Issue.
It has Been sitting in my Drive way since then.
I went to use it for a Road trip the First time 7 days ago, and The Fuel shut off Solenoid started acting up on me....Killed fuel after about 1/2 hr run time...I limped it off the Hwy.
Put new Fuel Filters on it thinking that was the issue first, Turned it around Head home, And it shut off on me again...
We pulled the unit Off, and Get it home. I bought a New Unit, same issue, and it is Random...? one time 25 mins, then only 10, then 2 hrs...?
I tested many things, thinking I had a Dead short somewhere...I think I have ruled that out now.
I think I have Determined that the Fuel shut off RELAY in the BAck of the Bus is Getting its Feed Power thru Wire number 193...? A red or red with black trace. But....? What I do not know , is where this wire comes from or goes to on the Bus or Motor...?
It either goes into a MODULE hiding somewhere, or direct to a Sender unit on the Motor..?
If Anyone has a Schematic of the Engine to Fuse/ breaker Panel wiring....I would Greatly appreciate a copy....
I read another thread where you guys Have Bypassed this unit, but I have much travelling to do, so i would Like to get to the root source of this Random Kill....
Many thanks in advance.
