I found an old Heathkit in the attic a month or so ago and decided to try my hand at building it. I'd never soldered anything more than some speaker wires, so I figured it'd be a good project to learn on.
I get it all assembled and do the preliminary wiring check before I plug it in. It says to connect my multimeter to the power cord and to a particular resistor. I'm supposed to get a reading of 2.2M ohms when I do that, but the meter reads off-scale most of the time, occasionally flashing 1.7-1.9 MOhms at me.
It looks like I've got everything soldered correctly with no bridges, so I'm stumped. Why wouldn't I be getting a constant reading on the meter? Can electronic components go bad? This kit is probably close to 30 years old.
