Default Re: Yamaha ydre wont't run

There are two weak points on the YDRE: Motor and Controller. I would first suspect that the motor is shot - brushes worn down to nothing. (if it's the stock Hitachi motor) Does the reverse buzzer work when you put it in reverse mode?
Measure the resistance between the two armature posts. Should be very low.
