• Which way does this electrical check-valve
work?: There will be a band on one end of the
diode. The band indicates the negative side of
the diode
• Most DVOMs have the ability to test a diode.
13. Testing a diode:
13a. Isolate the diode in the circuit.
13b. Set the DVOM to the diode or
Ω scale.
See Figure 9.77.
13c. Attach the negative lead of the DVOM to
the side of the diode with a band on it.
13d. Place the positive lead on the other side of
the diode.
13e. There should be continuity.
See Figure 9.78.

13f. Switch the leads.
13g. The meter should indicate no continuity.
See Figure 9.79.
13h. If the results do not match the above,
replace the diode.
