This diode in your generator is an electrical one-way valve, converting alternating current (AC) into direct current (DC) for a stable and reliable power output. It is usually positioned near the stator and endbell. If the diode malfunctions or gets damaged, you might notice issues like inconsistent power output or voltage fluctuations when using electrical devices. A simple multimeter test can determine its functionality, where a proper diode should allow current in one direction and block it in the other. If it fails the test or shows signs of damage, replacement is recommended. For replacement, remove the rear power cover. Carefully detach the old diodes and cut each wire close to where it was soldered to the diodes. Strip about a quarter-inch of insulation from both wire ends and solder them to new diodes. Reattach the new diodes to the power cover. While performing the replacement, you can also add grease to the roller bearing and clean the area where the brushes make contact on the armature. Finally, replace the old carbon brushes with new ones, ensure all wires are properly connected, and reinstall the power cover onto the generator body. It is important to note that this OEM replacement part is sold separately from the carbon brushes, the capacitor, and any accompanying hardware.

Parts Used
Removed both diodes with small socket wrench and snipped each wire close to diodes solder connection. "Diodes are threaded through bottom of power cover"
Stripped about 1/4 inch from both wire ends and soldered to both new diodes and installed the new diodes back onto the power cover with the original nuts.
While the cover was off added grease to the roller bearing and cleaned the smooth area where the brushes make contact on the exposed armature.
with a small flat blade screwdriver, removed both old brushes at the front side of the power cover and replaced with new ones.
Be sure that (all wires are firmly attached to their connections) and reinstalled the power cover to the generator body.
This has repaired the loss of power production for this Generator.
