All tests are to be performed with the negative lead of the DVOM connected to the negative side
of battery pack voltage.

The positive lead of the DVOM is used to probe the controller connections. Leave connections
plugged in the controller

Armature will need to be rotated for this test. Jack vehicle up on the passenger side and rotate
the rear wheel by hand
