Urbestfriend thinks you may have posted in the wrong place. My search for a Boreem 350
is for a small electric scooter. If this is the case, your controller to run the thing may be bad.
You would have no CDI, Coil or Spark because you have no gas engine
?.
I was also given one of these bikes and ended up scrapping it because it was more expensive
to fix it than to buy a new one. The only advise I would give is:
1) Are your batteries still good.
2) Are there any other loose wires.
3) If you jumper the batteries to the motor itself, does it run ?
4) Controllers are probably $25 to $50.00. Mendelson's in Dayton, Ohio
carries some electric scooter parts.
