1= Not rexactly, however you must LUBE the deck belt, this a problem because of lack of maintenance, probably a deck worn, this cause enough friction shut down the machine for protection electronic.2)LUBE the rollers bearing.3)test the input voltage motor, if there are the motor need repair.4) measure the output voltage board, if there are NOT voltage, the board is faulty, see my personal TIPS, and see the block diagram. RUN the software calibration for diagnose, and troubleshooting. God bless you
