2-1.G572R/U Electronic Component Troubleshooting
Malfunction Failure symptoms Points to inspect and test Components to
replace Notes
Cannot turn on
When the display is not lit, I
exercise on the product, but the
display still does not light.
1. Inspect all cable connections.
2. Inspect whether alternator produces

value.
1. Inspect all cables.
2. Inspect the optic sensor. Make sure the
distance between the sensor and the
reflective sticker is 3-8mm.
3. Inspect the optic sensor LED on the drive
board.
4. Replace the optic sensor.
5. Replace the boost converter.
1. Optic sensor
2. Drive board
No resistance When I exercise, there is no
resistance. 1. Inspect whether the alternator startup functions normally.
2. Inspect whether the alternator fuse on the
drive board is burnt.
