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

Method 2.
1. Inspect the relay operation using a battery (12V) as follows:

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