Ok this is good and you are measuring the resistance from the wiper to the chassis and not from the wiper to the other end of the pot? ? Or another way to measure it is with the coil wire disconnected measure the resistance from the chassis to each end of the pot. One side should be 10k and the other 0.

Quote:I hooked the wire back up and there is no response on the resistance on the volume control again.

This how it should be. The coil is a much lower resistance than the pot. To the meter it's just seeing the coil because it looks like a short by comparison to the pot.

I was down in the basement in my dad's
workshop. Perusing his Sam's Photofoacts
Vol 1-50 admiring the old set and trying to
figure out what all those squiggly meant.

Now I think I've got!
