During normal operation, the RED light will be off and the GREEN light will be on steady when no
speed signal is present and flashing when a speed signal is being received.
If the RED light is flashing rapidly, then the cable is stuck and not able to turn. Some stock
speedometers may become very stiff at low temperatures (below freezing) and not allow the cable to
turn. Make sure your stock speedometer is in good working condition.

Solution
Check the power and ground wires
on the ECD-100.
It should be 11-15 V dc.
for normal operation.
Check the cable for kinks and verify
the speedometer turns freely.
Test for 1-20 volts AC at the white
wire with the wheels spinning.
Make sure both the speed sensor and
ECD-100 are grounded at the same
location.
Check speedometer cable connections
at both ends.
Route the speed signal and tachometer
wires away from each other to avoid
interference.
Make sure the speed sensor and
ECD-100 are grounded together.
Check speed sensor is operating
