You have a voltage drop all right, but it is not across the motor.  Connect
one meter lead to a solid ground and take voltage readings at every connection
point from the motor terminal back to the line side of its fuse WITH THE
CIRCUIT LOADED.  Or start at the supply side of the fuse and go towards the motor.
Loaded down, nearly all of the voltage drop will appear across any high
resistance connection, whereas, unloaded you can take voltage readings all day and
never see a problem.
