PTT MOTOR RELAY
Two methods can be used to test PTT relays.
Method 1.
Measure resistance between wiring leads of the relay.
09930-99320 : Digital tester
Tester range :
WW
WW
W (Resistance)
Method 2.
Connect the wiring leads of the relay to battery (12V) and check
relay operation.
09930-99320 : Digital tester
Tester range : (Continuity)
When there is continuity between terminals 1« 2« 3, the
unit is considered to be without defect.
With Black lead wire connected to the battery negative (–) ter-
minal and Light blue or Pink lead wires are connected to bat-
tery positive (+) terminal there should be continuity between
2« 3« 4
..
..
.
With the lead wires disconnected from the battery there should
be no continuity between 3« 4.
The relay is considered to be without defect if continuity test
results are as stated above.
