i was just given a gently used mx-350 dirt bike. lady said it ran fine, stored it for the winter and now it won't work. 1st thing i did was test the batteries, multimeter reads them at 24.0 volts. when everything is together, it won't move, the motor just makes a humming sound like it is trying to go. i then hooked the batteries straight to the motor, thinking it was a bad controller or throttle. same thing! should 2 12v batteries in series read 24.0 volts? i thought it should read around 25 or 26 volts. any help would be appreciated, even if it is a guess, this thing needs to be done by friday, as it is my sons b-day gift. thanks!
