I was in the Navy, submarines. We had to attend annual "battery compartment" training. Our battery was a series of cells that made 450vdc. Part of the movie portion was a ring welded to a wrench...

I just fried the tip of my finger off a few weeks ago on the positive lead of my (former) truck's alternator.
And I knew better...

Not sure without looking at it, but I'd imagine key on position is opposite of key off position. Voltage on or off respectively.

I'm not familiar with the Cummins injector pump but if there's any kind of lever, it would be relaxed when off, not quite so relaxed when on, then move in relation to the accelerator.

My Cat is fly by wire, can't wait to dig into that thing...

Not trying to bs you, but I'm at work and don't have one in front of me to explain it...

Just see if it moves when the key is turned.

The 8.3 cummins usually has a large solenoid mounted on the rear end of the Injection Pump. The solenoid shaft is vertical, Pulls up for run, connected to an arm on the IP. Up is run, down rotates a shaft into the governor housing and blocks fuel flow for shutdown. I have a ford LN8000 dumptruck with the 8.3 and intermittent wiring issue somewhere with that solenoid. It's a dual coil solenoid, Pull up coil is much higher current, hold coil is smaller and pulls less juice. in mine the pull up portion refuses most days. I turn on power, reach under the fender and crank the solenoid into the run position until hold coil grabs and good to go.
I personally still prefer the cable and red handle on the 5.9 in my TC2000 "Tool Bus" No wiring hassles and I can shutdown whenver I want. To a certain degree is offers theft protection, most kids would have no clue what it's for or why it just cranks!!!
If the solenoid or wiring is bad and you just need it running, pull the solenoid up, wrap a piece of bailing wire around it and go crank it. Just have to pull the wire off at the end of the day for shutdown.
