Congrats, Erik.

Hi Don,
Yeah, I don’t often perform measurements on components already installed in a
circuit, so the behaviour was confusing. I thought I bought a nice DMM but I
guess it was just a fluke… ;-)
Anyway, I got it finished and everything is operational, now just have to wait
for the IC-705
Erik,
Yes, using auto ranging on the DMM can cause false readings. Try to set
the fixed range a bit above the highest expected resistance for the best
results. It all depends on the voltage the DMM applies to the circuit.
Too high a voltage can make ICs and transistors conduct causing a
Hi Don,
Everything appears correct and in place, already used magnification to check,
and individual resistors all seem to measure correctly. I still think it's my
multimeter in auto mode. I went back and retried the initial test using manual
ranging and if I set the range to 600K it shows a
Since that is the case, check the value of the resistors and check out
the soldering under magnification.

Hi Don,
Nope, D3 and D4 are correct, and the LEDs check out per the test...
Erik,
Check and double check the orientation of the diodes. That is the most
likely reason for you measurement results.
