5. Product Description
This voltage regulator rectifier is an aftermarket replacement part for select Harley-Davidson Touring / FLH / FLT models. It is designed to help regulate charging voltage in the motorcycle charging system and replace a failed or damaged original regulator.
A faulty voltage regulator may cause symptoms such as battery not charging, low voltage, overcharging, weak electrical output or charging system warning issues. Before replacing the regulator, we recommend checking the battery condition, stator output, ground connection, fuse and wiring harness to make sure the charging system fault is correctly diagnosed.
This part replaces reference numbers 74505-09 and 74505-09A. Please compare the original part number, connector style, mounting points, wire length and overall shape with your old part before ordering.
This is an aftermarket replacement part and is not a genuine OEM part.
