Replacement Voltage Regulator

 

Replacement Onan Generator Voltage Regulator

This part number is an improved, direct replacement for the voltage regulator used in several models of Onan "Commercial" Series Gen Sets.

These generators were often installed in bucket trucks and other commercial vehicles. Our metal case design features indented sides to allow a socket to fit over the mounting bolts and thus make installation easier than with the original case. Other features include improved circuit design and better heat dissipation (through gel encapsulation and larger internal heat sink). Unlike the epoxy encased originals, this one can be rebuilt.

It is built in the USA and backed by a 2-year Warranty.

This regulator is used in the following Onan Commercial Gen Set Models:

BGD: Spec J & later
NHD: Spec J & later

Item Number: 305-0911 Price: $547 Price last updated 9/14/2026 Shipping Weight: 2 lbs. This item normally ships in approximately 3 days or less.
