To check the STATOR. Turn ignition key switch OFF, then disconnect the voltage regulator connector from alternator stator wiring. THEN connect an ohmmeter set on the RX1 scale with one lead into either of the stator sockets and the other lead to a good ground. And test for continuity - a good stator will show no continuity (0 ohms) across either stator socket - any other reading indicates a grounded stator which must be replaced. THEN remove the ground lead and insert lead it into the other stator socket - the resistance (with ohmmeter still set on the RX1 scale) should be 0.1-0.2 ohms - if the resistance is lower a stator short is indicated. Which means that the stator is damaged and must be replaced. - if the resistance is higher (OL on meter), an open is indicated and again, the stator is damaged and must be replaced. You should check socket 1 to 2 then 1 to 3 then 2 to 3. ( If you have a two wire stator you would check 1 to 2)
Before testing short out the ohmmeter leads against each other and if they do not produce a reading of 0 ohms subtract the reading you do get from any readings you get doing the stator checks in order to get accurate stator circuit readings, otherwise you may have out of range reading due to the internal and/or lead resistance of the ohmmeter.
To check the 2000 FLSTF STATOR. Turn ignition key switch OFF, then disconnect the voltage regulator connector from alternator stator wiring. THEN connect an ohmmeter set on the RX1 scale with one lead into either of the stator sockets and the other lead to a good ground. And test for continuity - a good stator will show no continuity (0 ohms) across either stator socket - any other reading indicates a grounded stator which must be replaced. THEN remove the ground lead and insert lead it into the other stator socket - the resistance (with ohmmeter still set on the RX1 scale) should be 0.1-0.2 ohms - if the resistance is lower a stator short is indicated. Which means that the stator is damaged and must be replaced. - if the resistance is higher (OL on meter), an open is indicated and again, the stator is damaged and must be replaced.
Stator Check
1. Turn ignition key switch OFF.
2. See Figure 1-18. Connect an ohmmeter.
a. Disconnect voltage regulator connector from alternator
stator wiring.
b. Insert one ohmmeter lead into either stator socket.
c. Attach the other lead to a suitable ground.
3. Test for continuity with ohmmeter set on the RX1 scale.
a. A good stator will show no continuity (? ohms)
across either stator socket.
b. Any other reading indicates a grounded stator which
must be replaced.
4. See Figure 1-19. Remove ground lead. Insert lead into
the remaining stator socket.
5. Test for resistance with ohmmeter set on the RX1 scale.
a. Resistance across the stator sockets should be 0.1-
0.2 ohms.
b. If the resistance is lower, a short is indicated. The
stator is damaged and must be replaced.
c. If resistance is higher (OL on meter), an open is
indicated. Stator is damaged and must be replaced
Now I will not swear that the resistance numbers are correct for your sporty but I would think that the same applies, less resistance means a short.
