b. General test procedures.
You must determine the type of test to
identify the actual bad item of equipment, and the test points for these
Troubleshooting techniques for this type of defect are voltage
measurements, followed by continuity checks.
c. Test procedure 19. The first test point (TP1 of Figure 48) is at
the MT-1029 J24 pin J. Remove the RT from the MT-1029 and measure voltage.
If 22-30 volts DC is measured at pin J, the RT is bad.
IDS for repair.
If no voltage is measured, more tests are required.
d. Test procedure 20.
The next check is at (TP2 of Figure 48).
Disconnect CX-4723 from the AM-1780 J-501.
multimeter, check continuity between the MT-1029 J24
pin J to
pin D of the open end of the CX-4723.
indicates zero ohms, the MT-1029, J-3513 and CX-4723
The AM-1780 is bad. Send to IDS.
If your meter indicates - ohms (open), the MT-1029, J-3513, or
CX-4723 is bad.
e. Test procedures 21.
The next test point (TP3 of Figure 48) should
be at J22 of the MT-1029.
Disassemble the MT-1029 and remove P1 of the J-3513.
Measure continuity of the MT-1029 J24 pin J to J22 pin D.
your multimeter indicates infinity, the MT-1029 is bad repair it,
if possible, if not send to IDS.
