Baja BE500 Electric Scooter
Recently had to replace the drive motor assembly, old one seized up solid. Also had to replace the batteries. Now it won't run. When I twist the throttle I get a short duration growl then nothing except a short jerk as if the motor is trying to run backwards. I switched the wires and it ran bacwards OK.
I am looking for a service manual for this machine.
Anyone out there seen one?
Sadly, the BE500 is just like many other e-bikes out there..... no support from the chinese manufacturer, and even less help from the people that imported them, or any distributor that placed them in retail businesses. You are sort of on your own, to a degree. Dont let that stop you. I cant remember where, but, there are some posts about diagnosing motor/controller/hall sensor wiring issues. First off, the juice in these things can seriously hurt or kill, BE CAREFULL. Always disconnect the battery, I mean, take it out of the bike to work on even one wire. If the part was an exact replacement motor, then it may be as simple as figuring out the hall sensor wiring. A bad controller in some cases can mimmick a bad motor, how did you determine which you had? Also possible is , the contorller is shot too. Switched wires? which wires did you switch? If the motor responded perfectly, aside from direction, its just a matter of finding the right combination of phases on the hall sensors to get you going forward,,, maybe.
Glad to see your post, but have little help to offer. Working on a BE500 project as well. Not much to report as yet. Need batteries to test the unit/electronics before spending too much money for new battery packs. Good luck.
