Remedy:
Measure the voltage at the battery without the engine or charger run-
ning. The reading should be a minimum of 12.4 volts. If not, the bat-
tery needs charging or possibly replacing. Measure the voltage at the
Processor. This reading should be not more than 0.20 volt below the
measured battery voltage.

SYMPTOM - NO AUDIBLE TONE AT A CONTROL HEAD WHEN SYSTEM
IS FIRST TURNED ON, BUT OTHERWISE WORKS PERFECTLY.
Cause:
A)Incorrectly wired eight-conductor cable.
B) Defective sound transducer.
Remedy:
A)Verify connection of the black wire to Terminal 1 in the Proces-
sor and Terminal 1 at the Control Head. Verify connection of
the red wire to Terminal 3 in the Processor and Terminal 3 at
the Control Head. In addition, the red indicator light would not
work if the red wire was loose or incorrectly wired. Check for
loose or corroded connections.
B) Measure the voltage at Terminals 1 and 2 of the Control Head
(do not depress the transfer button). The voltage should fluctu-
ate at a steady rate. If a fluctuating voltage is not measured,
replace the Control Head, or install a Control Head Repair Kit.
1.6
SYMPTOM - AUDIBLE STEADY TONE FROM ALL STATIONS. CANNOT
GAIN COMMAND AT ANY STATION.
Cause:
A)Low battery voltage at the Processor.
B) Component failure on the Processor circuit board.
Remedy:
A)Check the battery voltage at the Processor. If the measurement
is less than 8 volts, replace battery or correct source of voltage
drop.
