How to test the stator
I soldered wires to by pass the stator plug connector.
If you suspect your stator to be bad, here is a test procedure put together by Ken Chapin with
Gold Wing Road Riders Association.

GL 1000/1100/1200 Stator Testing Procedures
For the purpose of testing the Stator assembly, use the following procedure:
1. check the ACG coupler for discoloration, which indicates overheating and it is faulty. This is the connector to the immediate left of the battery and consists of 3 yellow wires. If the connector is found to be discolored and/or brittle from overheating, an ACG Coupler Repair Kit (Part # 31105-ML8-305) is available from your local HONDA dealer. Ensure that the coupler is well packed with dielectric grease. An alternative is to remove the coupler altogether and ?hardwire/solder? the yellow wires together. This method is also acceptable but does make future testing somewhat difficult and would require cutting of the wiring.
2. unplug the ACG coupler and start the engine.
WARNING: Unplugging the ACG coupler while the engine is running can cause sparks which can ignite flammable fuel vapors. You could be burned. Do not unplug the ACG coupler while the engine is running.
3. with a Voltmeter, measure the A.C. voltage between each pair of the three (3) yellow wires in the ACG coupler that leads to the rear of the engine and enters through the rubber grommet leading to the Stator. Conduct the voltage tests between wires A and B, A and C and finally between B and C. With the engine at a steady 3,000 RPM, the voltage should be at least 50 Volts of A.C. voltage from each pair (or phase).
4. if the test indicates 50 Volts A.C. voltage or more from each pair (or phase), the Stator does not require replacement. However, if either pair of wires does show less than 50 Volts of A.C. voltage, replace the Stator.
5. Continuity tests must also be performed to determine if the Stator has developed an electrical short within itself or if it has shorted to ?ground?. With your tester set on the Ohmmeter @ R X 1, check for continuity between each pair (or phase) of yellow wires, A and B, A and C and B and C. You should have continuity at all three pairs (or phases). If you find any one pair with no continuity, then this indicates an open circuit in the windings of the Stator and it requires replacement. Then check for continuity between each yellow wire to a source of ?ground?. You should NOT have continuity and if you do find continuity at any wire, this indicates a short within the Stator windings and requires replacement.
** for your Stator to be healthy, it must pass all of the above tests.
