• Inspect sensor wires for a short (staple in wire), correct wiring polarity (black/white wires
reversed), broken or disconnected wires, replace/attachas needed.
• Disconnect all wires from back of motor unit.
• Removesensors from brackets and shorten sensor wires to 1-2 ft (30-60 cm) from back
each of sensor.
