3.3.3 TROUBLESHOOTING – NO RESISTANCE OR INCORRECT RESISTANCE
B) If the ECB motor can move, the resistance can be adjusted. If the resistance is still too high, check the
gap between orange block and the bottom. It should be within 1-2 mm.
If the gap is larger than 1-2 mm, the resistance will be heavier than normal. Adjust the cable to the correct
gap range.
3. If all above conditions are ok, and the resistance is still too high, inside magnet is defective Replace the
ECB.
