— the motor should now run. If the motor runs before you release the
throttle, recheck the wiring.
G. Take the vehicle down off the blocks and drive it in a clear area. It
should have smooth acceleration and good top speed.
H. On vehicles that are intended to plug brake, test the plug braking by

letting up on the throttle. The vehicle should smoothly brake to a stop and
accelerate in reverse.
I. On vehicles that are intended to have plug braking inhibited, verify
that the maneuver in "H" produces freewheel coasting.
