I had a hunch it was wrong, I read the black lead on my old unit and it was blocking as it should, but the new one had no reading, until I tried it on the green wire, then it was blocking as it should. It’s like the green and black wires are transposed on this new rectifier. Thank you for the update.There are different types
Pre 1980 and after I believe ( It can differ a couple years little )
But most likely you got the Wrong one
Also one more question? Who would have the correct fit without issues?I had a hunch it was wrong, I read the black lead on my old unit and it was blocking as it should, but the new one had no reading, until I tried it on the green wire, then it was blocking as it should.

What do you mean by "it was blocking ....." ? You may have the correct unit but it just might be defective right out of the box. Many of the aftermarket units are low quality and expensive. Best solution is to build your own like in Jim's link.
The black wire reads on my older unit, when blocking as in one of Jim’s video I saw on You-Tube . When connecting the meter on the new unit No reads on the black wire , but I tried it on the green wire and Presto I got a read . It’s like they are transposed.

Yes the bike stopped charging , to the point where the new battery went dead, motor just stopped, I just purchased the machine a month ago here in Cincinnati. I checked the alternator rotor with it on the bike / making sure not to touch the stator housing for false ohm reads on the copper rings. It showed up at 1.7 ohms - I removed both brushes when doing this procedure last night. I thought for sure it was the rectifier unit, but the brushes are low I’ve noticed. I retested the old rectifier and it’s showing good, I purchased the new rectifier without doing Good research on this new forum I just joined.I don't understand what you mean by "blocking". When testing electrical connections, that's not a term I'm familiar with. The black wire is the ground wire. I don't think you get any reading on it. The green wire is the output from the regulator to the outside brush. In the case of your later alternator, that would be a switched ground signal. The regulator switches the ground on and off to the alternator to control the charging output. I don't know if you'd get any reading on the green wire unless the unit was powered up.
Why are you changing this out? Did the bike stop charging?
1.7 is bad, should be around 5 Ohms.. It showed up at 1.7 ohms
Thanks Greg.1.7 is bad, should be around 5 Ohms.
@Jim can advise you where to get your rotor rewound. He does good work.
Good afternoon Jim, thank you very much for the detailed info. I am interested in having my original alternator rewound, Today I purchased the BWD -R914 voltage regulator off E-bay . So now onto purchasing the Windy Nation 30-35A part. I’m located in Cincinnati-Ohio..Thanks Greg. View attachment 186661
Yes, 1.7Ω's is bad. If you want a rewound rotor, have a read here.
Send me a PM to get the ball rolling.I am interested in having my original alternator rewound
