It seems that I have caused problems with my e-15 by moving the speed
control to reverse while rolling (not necessarily under power) forward.
Can
moving the speed control into reverse while the motor is still turning
forward cause a blown reverse relay?
Yes. It causes arcing and eventual welding of the contacts. There's
a circuit on the control board to prevent this from happening, but it
doesn't work well enough.
