NOTE:
If the generator does not engage or if it makes a grinding noise after the startup procedure,
shut the truck off and wait five (5) minutes before attempting the procedure again. Excessive
start attempts will cause the PTO solenoid to over heat. Once the solenoid has over heated,
the generator will not engage until the solenoid has cooled sufficiently.
