If the meter indicated zero ohms, the CX-13063/U is good and the
J-3514/U is bad. Send to COMSEC maintenance for repair.
g. Test procedure 38. If 22-30 volts DC is measured at TP2, reconnect
the CX-13063/U to J2 on the HYP-57 before going to TP3.
To measure voltage at TP3, separate the HYP-57 from the KY-57.
Measure voltage
between pins 5(+) and pin 1(-) on J1.
If the
meter indicates
no voltage, the HYP-57 is bad.
Send to COMSEC
maintenance for
repair. If the meter indicated 22-30 volts DC,
the HYP-57 is
good and the KY-57 is bad.
Send to COMSEC
maintenance for
repair.
