Speaker Harness Test
Ground Condition
(1) Disconnect speaker feed wires at radio con-
nector and each individual speaker.
NOTE: When reconnecting the speaker harness to the
radio, be sure the antenna lead-in cable is fully engaged
in the radio socket
(2) Connect one lead of an ohmmeter to the speaker
feed wire and the other lead to a good ground. An in-
finity reading should be indicated. Check each individ-
ual speaker wire in this manner.
(3) If resistance is indicated on the ohmmeter, the
wire being checked is grounded.
NOTE: Grounded speaker harnesses are generally
caused by screws piercing wire harness.
