• "BAT" stays on when display is connected to harness cable.
The wire connections to the harness cable are probably not correct. Inspect
your wiring. See 1-5 on page 21.
• "BAT" comes on when ignition is turned off and display is plugged into harness
cable.
The DriveRight display is connected to switched +12V instead of
unswitched +12V. Connect to unswitched +12V. See Step 2 on page 7.
• "BAT" appears when display is connected to harness cable but flashes off
when dot appears. (See "Initial Test" on page 18 for a description of the dot.)
The black and white wires from the sensor are connected backwards to the
black and white wires of the harness cable or the ground connection to the
vehicle's chassis is spliced to the white sensor wire. Inspect your wiring, see 1,
2, 3, and 5 on page 21.
• Dot does not appear when display is plugged into the harness cable and wheels
are rotated ("BAT" is off).
The sensor installation may be incorrect. See 6 on page 21.
• Speed is zero when driving.
It is possible that you simply have not calibrated the DriveRight (see the
User's Guide for instructions.) If your speed remains zero, the sensor may not
be close enough to or properly aligned to the magnet mount. Inspect sensor
installation with vehicle resting on its wheels. Check positions of sensor tip and
magnet mount. If not aligned, see 6 on page 21. If sensor appears aligned
properly and speed remains zero, use "Sensor Wire Continuity Test" on
page 23.
• Speed reading is intermittent while driving at constant speeds.
The sensor mounting bracket may be interfering with the magnetic field.
MAKE SURE THE SENSOR END PROTRUDES 3/4" (19 mm) FROM
THE SENSOR MOUNTING BRACKET.
Otherwise, there may be too much movement in the driveshaft or in-board
CV joint causing the magnet mount to be too far from the sensor tip on
occasion, or the connections may be loose. To fix this problem, inspect sensor
installation with the vehicle resting on its wheels. Check positions of sensor tip
and magnet mount. If not aligned, see 6 on page 21.
• Move sensor and magnet mount closer to universal joint on rear wheel
drive vehicles.
• Check vertical alignment of sensor bracket if bracket is mounted on the
vehicle chassis, consider mounting bracket to engine.
• If the brackets are properly installed, use "Sensor Wire Continuity Test" on
page 23.
• Screen goes blank when attached to harness cable.
The display is going into "sleep" mode. This only only happens when the
unit is running on battery power. Inspect your wiring. See 1-5 on page 21.
