5. Unsolder the stator coil lead wires. Remove the stator assembly.
CAUTION
Never heat the lead wires long to prevent damage to diodes.
6. Disconnect the capacitor from terminal liB. II
7. Loosen the screws fixing the rectifier and remove the rectifier.

a. Connect a circuit tester (ohmmeter) across the lead wire and case of the diode to be tested. The diode
is considered normal if its resistance is large in either direction and small in the reverse direction.
b. If there is equal resistance in both directions, the diode is suspected to be defective. Replace the rectifier
assembly.
c. Check every diode for conduction.
