Diagnosing problems with a multimeter
Is someone available to show me how to identify witch components of my e bike are not functioning properly with a multimeter.
Turn the multimeter to the 20V setting.
Put the probes on each of the battery cells.
Post the readings back here!
check the "motor interrupt" functions of the brake levers. If the levers are preessed, or think they are, you wont get any motor function.
Think "simple", the brake levers, or at least one of them, has a small switch in it that is activated by the grasping of the lever and pulling it. When that happens, the switch position changes. If your brake lever was damaged by a fall, it is possible the bike may "think" the brake is on, and not allow the motor to run.
Ok, by "it didnt work" I guess you are saying the switch is still working normally. Thats ok, at least we know one important safety feature works. Search the forum for testing the throttle. There are some good threads on this. Another idea is to start at the motor, and follow the wires to the controller. There should be two different types- 3 large wires, and some smaller ones. Make sure there is no burn spots, or insulation missing, and that all connectors are nice and tight. If the wires come out the same side as was face down when the scooter fell, they may have been damaged. Its also possible that the rain brought out a problem the previous owner had been experiencing.
