Ignition problem
Okay guys. Lets see who can help me on this. My Cat started tonight but will not shut off. Took the switch out and still no luck. Checked batteries and have 13.5 running. 1999 National Tradewinds ...

Normally a diesel engine has a solenoid for shut off.
When you turn the key on it causes the solenoid to open letting fuel to the pump.
You might have had a sticking solenoid. ???
Years ago I had a CAT engine in a Boom Truck. Once warmed up if I shut it off for any length of time the pressure would build up and it would not re-start until cooled down or I opened a fuel line and drained pressure on the solenoid.
I learned to shut it off then turn key back on if I was going back out with the truck.
At the time I was too broke to replace the solenoid!
