Hard to test the motor in the awning as the motor is in the roll of the awning. and the awning moves.
How you usually test a motor is to see how much voltage drop their is, at the motor, when running. The higher the voltage drop, the more motor is trying to work. It should not drop more than 1v if running as it should. Example...my 10 amp water pump drops only .3 volts or so when running.
Side note...A voltage drop can also mean poor, damaged, etc wiring. Wire must be the propor guage for the application and amp draw.
But it will be hard to test either way.
Hope this may help.
