Yes, I see that, thanks. You are gradually managing to teach me the fundamentals of electric circuits under the hood (Business Admin grad here), and I confess it's fascinating and gratifying to understand. So, here's my layman's read on what you just told me: a circuit that requires the ign key to be on could potentially shut the ign off if shorted, but in the particular case of R15, the relay isn't even operating unless there's adequate hi pressure at the drier, and even when it is operating, there's a fuse in the circuit that would blow before the ign would be affected. Ergo, not a hi likelihood that a short at R15 would manage to shut down the ignition. In contrast, F22 is on a circuit that's always hot with key on, and if the F22 creates a short, there's nothing left in the circuit to prevent the ign from quitting. If that's a correct layman's interpretation, I'm beginning to get the hang of this stuff.
