If the Power LED does illuminate when the ODU cable is removed, proceed as follows:
Procedure 7-6 Power LED does illuminate when ODU cable is removed
1
Remove the jumper (J905) found inside the PIDU Plus flap.
2
Measure the current with an ammeter placed across the two jumper pins. It
should be 10 mA with the ODU disconnected.
If the ammeter reading is incorrect, report a suspected PIDU Plus fault to
Motorola.
If all tests so far have succeeded, proceed as follows:
Procedure 7-7 Other power tests
1
Reconnect the ODU cable to the PIDU Plus.
2
Measure the current with an ammeter placed across the two jumper pins. It
should be in the range 300 mA to 1 A with the ODU connected.
3
If the ammeter reading is too high, the ODU may be drawing too much power,
or the ODU may be short-circuited. Report a suspected ODU fault to Motorola.
4
If the ammeter reading is too low, the PIDU Plus may be supplying too little
power. Report a suspected PIDU Plus fault to Motorola.
