Just because a generator cranks up every week for the set run time does not mean that the generator is functioning properly!
Most automatic generators have what the manufacturers call a weekly exercise circuit which cranks the generator once a week and runs for it approximately 15 minutes. This really does not exercise the generator, the unit must have attached loads in excess of 50% of output capacity of the system in order to truly get exercise. Additionally if the loads are not changing in levels of current, linkages nor electronic governors are tested or exercised!
