g. Test procedure 11.
If no voltage was measured at J24, the first test point (TP1)
should be at the vehicle commo power Bendix jack.
Remove the CX-10613 from the vehicle commo power Bendix jack and
measure voltage at the jack, pins A(+) and B(-) (Figure 31).
If there is no voltage at the jack, the vehicle wiring,
batteries, or connection is bad.
Troubleshooting the vehicle
wiring depends on local SOP.

h. Test procedure 12.
If 22-30 volts DC is measured at the vehicle
Bendix jack, reconnect the CX-10613 to the vehicle commo power Bendix jack
and remove the other end of the cable at the MX-7777B J3.
Measure voltage on the CX-10613 pin A or B(+) and C or D(-)
If no voltage is measured, the
CX-10613 is bad.
replace the cable.
If 22-30 volts DC is measured reconnect the CX-10613 to J3 on the
DC power TP1 and TP2 (no voltage).
