Procedure For Upgrading 12 Pole AlternatorAVDALSR087-1 21st August 2013 Procedure for modificationThe procedure to increase the alternator voltage is as follows.1. A schematic showing the current and altered wiring is shown in Figure 7.2. Disconnect the battery before you commence any work.3. Disconnect stator wiring terminals and harness wire ties, then remove retaining bolts holding the rear plateand stator assembly from the engine, as shown in Figure 1.Remove 4 bolts holding rear plate, gentlytap off dowels, leaving spacers andignition coils in placeFigure 1 – Rear plate removal4. With the assembly on the bench, use a heat gun to soften the Loctite on the 4 screws holding the statorassembly. Take care not to snap screws or damage threads: apply more heat of the screws are hard toturn. Remove stator. Note harness exit hole on rear plates so you can assemble in the correct orientation,see Figure 2.1 Issued By: DS Page: 4 of 8
