Diode Circuit Inspection
Tester
Connection
13-8, 13-9, 12-11, 12-14, 15-14, 16-14
The resistance s hould be low in one direction and more
than ten times as much in the other direction. If any diode
shows low or high in both directions, the diode is defective
and the junction box must be replaced.
NOTE
○
The actual meter reading varies with the meter used
and the individual diodes, but, generally speaking, the
lower reading should be from zero to one half the scale.
