Ok finally got around to testing the resistance in the stator and field coil.
My manual says that the resistance of the stator should be 0.5 - 0.6ohms @ 20degrees Celcius. The reading I got was 1.2 measuring across the 3 connectors.
The field coil resistance is 2.7 - 3.3 ohms. I got 5.5ohms.
Obviously the reading is out of spec, so my question is..... is it time to open the wallet up and get new parts?
