Alternator / stator for scooters with Morini or Derbi motors with 79mm ignition plate with 4 connecting cables. Delivery consists of the stator and the cable set. Completely ready for installation. Defects in the alternator can be very difficult to diagnose without expensive special tools. Burned CDI ignition units, regulators, ignition problems or poor battery charging are often caused by a defective alternator. It`s rare that the damage can be repaired and only a complete replacement is the answer. Please make sure to compare the connections!
