Exactly. Disconnect the green plug on the back of the alternator. With a volt meter check the black/yellow wire, it should show battery voltage, then the black wire, start the engine and after 8 to 10 seconds it should show approx 5 volts.
Don't know what you mean by "replaced the rectifier", it is built into the alternator.

Yes it does the black and yellow shows 12.3 volts then with the plug unplug the black wire show .5 with the motor running

It was 5 volts could someone tell me it the regulator/rectifier relay box have anything to do with this changing problem
First, lets clear something up...
the 1800s use an Alternator, period.
there is not, and never will be, a Regulator/Rectifier found on an 1800.... those only exist on 4 cylinder bikes.
Alternators have the 'Regulator' built-in inside the case of the Alternator.
the Field needs that one wire to feed voltage to it, so that the Alternator can generate power.
the ECM keeps that wire at Zero volts until after the engine has been running for ~5 seconds.
that is why there is a delay after the engine is started, before the voltmeter ( if on the bike, or a DVM attached to battery ) will start climbing from ~12 volts up to 14.3 volts.

What are you talking about? It doesn't have anything to do with the charging system whatever it is but would like to know what you are referring to.

I’ve been told that this is the rectifier that tells the alternator to change or not over charge the battery
mine is a 2002 and it has the delay, they all do
The 2017 as well.

Maybe, that's why I asked the question can he tell if the alternator is turning.

Ok now if I test the voltage coming out of the battery with the bike running then the voltage keeps going down but if I test the voltage coming out of the reverse regulator then it is going up where it is suppose to so where do I go from here
yes alternator is turning like I said the volts is get back to the reverse regulator but it’s not going from there to the battery
I'll try also.
The REVERSE REGULATOR has nothing to do with charging the battery. It is a reverse regulator because it regulates the speed of the bike when you use reverse. Nothing to do with the charging system. That is a picture of a part of the reverse system for backing the bike up in reverse.Why do you think it is not charging? How did you diagnose and come to the conclusion it is not charging rather than an issue like a bad battery etc?. Are you aware that for about 12 seconds after you start the bike, the alternator does not charge? This feature gives the engine a short time to stabilize after start up without the heavy load of the alternator. That means you should not test the alternator for a couple of minutes after you start the engine.
If he is not using a Battery Tender in between all this "engine starting" to test things, the battery is too low to be meaningful.
as just said, it takes about 15 minutes for the battery voltage to return to near normal at 14.3 at roughly 2500-3000 RPM
even at idle, it will charge up to 14.3 if you watch it for a while.
If it doesn't, then the battery most likely has some bad cells in it.
