Hey all - thanks for the input!
I was able (with Jeff's help) to locate the switch (in the image if it renders).
I've had that bay open before, but never took note of that switch. The front outside bay, with all the fuses, just below the drivers seat.
Snow will fly here in NH tomorrow - so I suspect, when I put the batteries back in, in the spring I'll take the next step to seeing if there are additional niggles that need to be worked out.
