How to use the multimeter to measure the good and bad of the electric locomotive motor Holzer?
The multimeter to the sound file in Holzer's black black red needle needle Holzer (yellow, green, blue wire) as much as three numbers are digital is good (electric vehicle maintenance)
Method for measuring voltage accurately, the specific operation process is as follows, prop up the car to the rear thigh, vacated the power to open locks, with the negative probe table inserted anode motor Holzer, respectively, the positive probe inserted motor Holzer, when measuring the motor rotates slowly by hand, Holzer there is a change of the voltage, if the voltage too low or constant, that the corresponding Holzer bad
Voltage detection method: multimeter voltage in the 20V file, the black pen fine black, red pen are respectively connected with three signal lines, and the slow rotation of the motor, the multimeter reading should be 0V-5V alternating voltage changes, otherwise the corresponding damage to Holzer.
