furnace update

So yeah...nice furnace. Found that the 24V transformer primary was open too. Lots of issues in that old thing. Digging around in it, I see 1976 date codes all over. A bicentennial special.
Older than DeAnna.
Some guy installed back what I was 14 and working on getting a ham license, I suppose.
That guy is probably retired (or worse).

The stupid air purifier is hosed, the humidifier is hosed. Looking around I see why. Burned and corroded wires, which will be removed. I'm sure the end devices are bad too.

Got to drag out my my shiny new 20 year old Fluke amp clamp and meter and found that the fan draws 9.5 amps! Which is normal from what I read, but my God, that's a kilowatt of power! And we let it run year around to keep air moving. I'll be rethinking that scene.

I got things temporarily going with a new transformer and some alligator clip leads.
So the fan is OK, just the control circuitry was bad.

Have to button it all back up after I test the A/C and furnace functions.
