Electric car Holzer bad what symptom?
The electric vehicle has the following three places to have Holzer (bad, generally directly trades Holzer, Holzer is unable to repair!) Holzer, there are 3 wires, you use a multimeter to test the power is removed (usually for the other two red line) is a voltage output (if the switch is good two values: close to 0V or 5V; 0.8-4.2V linear continuous output value), no output or other bad. Of course, when testing, brake and release two of the movement, turn the handle and motor to make it manually turn up.
1, brake handle, if it is electronic brake handle, it is broken, the motor is not working, the electronic brake has two kinds, one is Holzer type, such as OH44E, is a switching signal, and the other is micro switch. Is usually braking time, the acceleration motor is not turned.2, turn the handle: the use of linear Holzer: OH49E, etc., the turn of the bad, generally does not speed up, or direct acceleration (speed).
3, Holzer motor broken (3 in all), the motor does not turn or turn the weak or abnormal sound (CACA), non professionals do not open, especially not open, because will damage the motor and water, if must be open to open whipped (because it has a strong magnetic force. Use a motor inertia open). Repair bicycles are generally open, it is best to find them.When you open it, you'll see 3 Holzer on the coil, usually switching Holzer, such as: OH44E, OH41, or OH41F. The best 3 are all changed.I hope I can help you!
