2008 October 18: Alternator testing and assembly (0.50 hours)
Updated:
- 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.
