Faulty Rotax 912 Alternator Wiring
Pieces of wiring from Rotax 912 alternator to voltage regulator/rectifier During repair of the motor mount, a major project, we discovered that the wiring of the integral alternator supplying power to the ignition module and the voltage regulator/rectifier had badly corroded. The above photo shows fragments of the wires going from the stator of the alternator to the voltage regulator/rectifier. Next is a photo of the wiring going from the stator to the ignition module. Here, too, the insulation has broken off and the wires are badly corroded. Defective wires supplying power to the ignition module Surely the damage must have been building up during several years. How could we have missed it during the annual inspections? The Answer There are two places where the wires are visible: At the voltage regulator/rectifier, and at the ignition module. These wires looked okay until a recent major repair of the motor mount, where everything firewall-forward had to be removed. A...
