Bridge rectifier is approx 1" square with 4 spade connectors, and has a hole in the center for mounting.

Replaces Onan 305-0718 or 305-0935.  Also can replace Coleman Powermate 0063232 and 0048677 with much better specifications!

This heavy-duty diode bridge can be used for many older Generac portable generators including model 8905-1 and 8840-1.

The original Generac part was a plug-in design, so you will need to remove the wires or connectors from the socket & re-wire to this rectifier with simple instructions included with this part.  This part looks totally different, but it will work in place of the original - assuming this is the only thing wrong with your generator. If you have a defective stator, rotor, brushes, or slip rings, this will not help of course.  PLEASE supply your Generac model #, item #, or product ID #, whichever is all numerical (all numbers - no letters)

Replaces these original obsolete Generac and Briggs & Stratton part numbers if re-wired correctly:

  • 022695000A
  • 00728293 or 007-28293 Dometic
  • 66850
  • 66850GS
  • 79569
  • 079569
  • 79569GS
  • 28293
  • 028923
  • 28923GS

NOTICE: Because the terminals will be exposed there is a risk of electrical shock!  We recommend you fully insulate each terminal, or relocate the recitfier to a different location that is not easily accessible while generator is running. Also assure it is mounted against a metal surface as a heat sink, or at least in the cooling air flow of the generator.
