1. If the array or antenna fails to turn, turn the power off and investigate.
2. Verify that the blue and green power control wires in the MDS cable harness are correctly
terminated and connected using one of the recommended termination methods described in
"Radar power control" on page 14 (direct connection, SPST switch, or relay control using the
Remote Power option from the navigator.)
3. Check the MDS box scanner motor fuse.
4. Open the dome or array and perform an internal inspection.
5. Check to make sure that nothing is interfering with the motor and gears, is binding or
preventing the antenna from turning.
6. Check for any disconnected, pinched or broken wires.
7. For older open array units, check for worn or broken motor brushes.
8. Verify that the scanner cable is correctly pinned, all wires are in the correct locations and the
connectors are correctly locked to the mating connectors on the modulator board.
