i. Test procedure 13.
Remove the CX-13089 from the MX-7777B and
measure voltage at J2 on the MX-7777B pin A(+) and pin B(-) (TP3).
If no voltage is measured, the MX-7777B is bad.
Send to IDS for
repair (Figure 32).
If 22-30 volts DC is measured reconnect the CX-13089 to J2 on the
MX-7777B.
Disassemble the MT-1029 and remove the CX-13089 from J22.
Measure voltage on the cable pins B(+) and A(-).
If no voltage is measured
the CX-13089 is bad.
Repair
and
replace the cable.
If 22-30 volts DC is measured the MT-1029 is bad.
Repair if
possible, if not send to IDS for repair.
