• I spent some time reading about testing the alternator's rotor and stator in the Moto Guzzi Workshop Manuals. Then I performed the following tests:
  • Rotor field winding resistance: should be 3.4 ohms; mine fluctuated between 3.3 and 3.5 ohms.
  • Stator winding resistance: the text indicates that the resistance between all the stator winding exits (U-V, U-W, V-W) should be equal; mine were all between 4.9 and 5.1 ohms.
• With these tests passed, I thoroughly cleaned all the terminals and secured with new lock washers and nuts.
• I mounted the rotor to the front of the crankshaft, I spread a coating of grease on the tapered shaft and thoroughly coated the threads with anti-seize.
• I mounted the stator to the front of the timing chest cover, each bolt was thoroughly coated with anti-seize.
