billybob Active Member Jan 23, 2021 #1 I am working on replacing a part in a M-audio speaker and when I took out the ic that needs replacing I tested a zener diode that was right next to it the multimeter read around 14k ohms on both sides is this normal?

MacIntoshCZ Active Member Jan 24, 2021 #4 There is no need for removing parts from board first ... Unless you want relevant measurement.

Then you're reading through the rest of the circuit, and almost certainly not through the zener diode. You also don't test zeners on an ohms range, you need a diode test range - where it should test just like a normal diode.
