Ok, so then the wires are *designed* to work like that then? That is,
a sharp needle like projection pokes into the collection of wires at
the center of the spark plug lead. If that's the case, then the wires
are probably good.

If i'm not seeing spark at either the points or at the end of the plug
wires, does that mean the control board is the likely culprit? Or more
likely the various wires. I will take contact wire to the control
board and check the connections on each individual wire.

I am THIS CLOSE to just saying screw it and taking it to the Cummins
dealership and getting them to mess with it.

I wonder how much they'll charge, and how far that would get me
towards a new control board, new wiring harness, and new ignition
system. I can easily seem them just wanting to replace everything till
they got it working. Hell, even *I* could do that, I think.

Argh. How frustrating.
