Thanks for the video!I would expect you to have gotten a detailed instruction sheet, unless maybe this is not a correct replacement part.

The distributor should be able to help you I would think. You may consider returning it if they won't or if you find out it's not the right part for you.

I did a non-OEM replacement & upgrade on a 1972 Honda CB350K3, and I used a full-wave bridge rectifier that I bought at my local Radio Shack.

You can get one like the NTE53016 (200V 40A) for under $5 via Radio Shack here.

You would ideally need to refer to the wiring diagram in your bike's service manual to be sure you get it connected correctly.
GENERALLY, but not always, positive is red, and negative is black.
One easy way to find ground is by measuring between the wire under test and the frame or negative lead of the battery.

You may have to cut wires, and either solder it in directly or attach new connectors.

Any full-wave bridge rectifier has two AC inputs, which are interchangeable with each other. They go to your generator's output.

And you will have a positive output and a negative output, usually at opposite corners from each other.

Here is a schematic for a bridge rectifier:

The bridge will be marked, and typically the positive and negative are on opposite corners, and the other two corners are the AC inputs:

I have a cb 400 Project Big One. one of the three yelow wires on the regualtor rectifier socket has some burns. Is it the reason why my RR keeps failing? or is it just symptom of a biger problem? thnks


If the wires are burnt then the reg/rectifier is junk. It may test within tolerance with a multimeter but it isn't any good once they burn. Replace it with a known good one.

Regulator rectifier mid 90s hondas


you will know if the regulator/rectifier goes, if 1, all your lights go much brighter and blow when you rev the bike, or 2, if your battery is not charging. a simple test is to check the voltage at the battery with engine idling, should be about 14volts. There is nothing you can do to prevent the rectifier from going.

BAD TACHOMETER WIRE LOSE,NEED TO BREAK CIRCUT IN HEAD LIGHT ASSEMBLY TO STOP TACH FROM PICKING UP SENDER SIGNAL, IS SPIKING IN MY 2003 HONDA 750 NIGHTHAWK


Believe it or not, a bad battery or loose connection at the voltage regulator/rectifier can cause this problem. It is caused by the charging system surging.

Will not crank after a week . ridden daily


How old is the battery? This machine as I remember it had no kick starter. If the battery is in good shape, the next thing to check is the voltage rectifier and the alternator. Although, it may be some other part of the overall charging/electrical system, a new battery is probably the place to start.

Can the bike be "jumped?"
