g. Test procedure 31. 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 test point 3 of Figure 52, separate the
HYP-57 from the KY-57.
Measure voltage
between pin 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 indicates 22-30 volts DC,
the HYP-57 is
good and the KY-57 is bad.
Send to COMSEC
maintenance for
repairs.
