Proudly made in the USA

This solid-state silicon based rectifier is about 7 to 9% more efficient than the old selenium based rectifiers used in the 1970s and earlier.   Unlike other replacement rectifiers, all Oregon Motorcycle Parts rectifiers are grounded to the frame and to the green ground wire.  This additional ground is required for many Honda models.

It is aluminum-cased; epoxy filled and runs much cooler than the original part. If bolted down to the original bracket, no heat sink is required. Many of these old bikes (built before the lights on laws were passed in 1975) ran a balanced charging system and if you run them with the lights on all time, they will not keep the battery fully charged and this rectifier will do a better job of keeping the battery charged. This part is rated at 42 amps constant use while the rectifiers on most of the older bikes were only rated at 12 to 15 amps. This rectifier should outlast the original part by several times under normal operation.  This rectifier is strong enough to take a voltage spike 5 times what your bike is capable of making without taking any damage.

Replaces these old style rectifiers.

 

This rectifier has 5" leads and an OEM type male plug.  Oregon Motorcycle Parts uses only the factory type Japanese connectors and are designed plug right into your bike with no modification. Beware of cheap knock off parts using inferior parts and electrical connectors.

NOS means new old stock.  All Oregon Motorcycle Parts are new improved items not fake originals.

 

Guaranteed not to fail for the life of your bike!

The warranty is for repair or replacment only.  There are no returns on used parts.

 

Note:  The rectifiers in this auction are NOT for any 4 cylinder Honda.  If you need a rectifier for a 1969~1978 Honda four, click the "see sellers other items" and check out the 5 wire rectifier I list.

 I was a motorcycle mechanic for 15+ years and I provide free technical support get it installed and working including diagnosing the entire charging system. If you’re not sure you need this part, I will give pre-sales tech support. I’d rather loose a sale, than sell you a part that you don’t need.
