Do you have some friends to call? Someone out there has
to know how to use a VOM.

Heh heh ...

I know how to use a DMM as well as anyone here knows how to
use one. I have had Simpson (analog) ammeters and voltmeters
since I was a young teen, when I was making my own resistance
testing equipment long before consumer DMMs were common.

My Fluke 75 is a good meter, which I've had for something
like 30 years. So, *using* a meter isn't at all a problem.

The problem is knowing what measurements to take.

To that end, this control board summary is a start:

As is this wiring control schematic:

And, of course, as is the overall furnace circuit schematic:

All of which I'm new to, but, which I will print and pore over
to see what basic control and power inputs to test with my
trusty DMM.
