Is there a generic replacement for the onan bridge rectifier #305-0517?
Yes, call Mouser Electronics (800-346-6873)and ask for part # NTE5342. (or 583-MP354) (Mike Danford (judyd#aol.com) Digikey sells these bridges #MB2510WMS-ND FOR $8.84Can ($5.85US). This is a Microsemi part. This bridge has wire leads not Stak-On terminals so it should be easy to fit into a PC board.
