Repair of Diesel generator


The customer had reported a fault that the generator was cutting out after a few seconds.


On inspection, it was determined that the generator had no output. The Generator was taken off the vehicle and stripped down, finding a burnt-out alternator.

It was decided to recondition the engine as it had run 7000hrs, the damaged alternator was also replaced. The generator parts were individually steam cleaned to clear the residue left by the preservatives and the dirt from the working environment. The air, oil and fuel filters were replaced along with fitting a new water pump, charge alternator, fan belt and battery. The injectors were removed and reconditioned and a new Mecc Alte alternator was fitted.

On completion, a load test to 110% was successfully carried out.
