PTT MOTOR RELAY
Two methods can be used to test PTT motor relays.
Method 1.
Measure resistance between two lead wires of relay.

@ (Continuity)
(1) Without lead wires connected to battery, there should be
continuity between terminals 1, 2 and 3 but should be
no continuity between terminals 3 and 4.
(2) With Black lead wire connected to battery negative - ter
minal and Light blue (or Pink) lead wire connected to
battery positive + terminal, there should be continuity
between terminals 2, 3 and 4.
2. The relay is considered to be without defect if continuity test
results are as stated above.
