Completely failed the slap test. I tested the rotor before it went in and it was good.

.Mark, it seems like you have more than a few Gremlins. Have you gone through every connector on the bike? Clean, shiney, tight? Have you done continuity tests on every wire in the harness? With all those various intermittent problems, I'd concentrate on the common denominator first; the harness and all its connections.
.@DanielBlack, short answer no. I have tested the ones I have easy access to, others are completely buried. I just pulled the head light off and am about to test those. I'm a little concerned that I have a host of new issues after reinstalling a working rectifier. Do the three white wires coming off the rectifier and going to the stator need to be in a specific sequence?? The witting guide didn't say so.
.I have a multi meter from Harbor Fright, but have not done to much testing after the new rectifier has been installed. I really wanted to take this on vacation with me next week, not sure she will be trustworthy by then.
.Welp charged the battery, installed it, meter had it at 12.8. Started the bike let it warm up for a second, rev'd it up and the volts went down, let off the gas and it went back to 12.5. My concern is I have a more problems after installing the rectifier, I've lost continuity in my headlight, left blinker and neutral light, god knows what else,
.Luckily the previous owner didn't do anything to the bike. It only has about 17,000mi on it. I'm curently looking at a wiring diagram, and formularizing myself with it. I will definitely check the slip rings when I get back from vacation. God Bless America.
.2.5 OHM on the rotor, think I found the major problem gentlemen. I know I have a couple other bugs to stomp out, but found my major issue.
.Ordered rotor and puller from Mikes XS. Just put them in and still getting about 12.8 when rev'ed up. I know the rotor was no good and I know the rectifier was no good. I guess I need to keep crossing things off the list. Any suggestions on what I should be looking at next?
.Completely failed the slap test. I tested the rotor before it went in and it was good.
.So... now that I'm generating electricity again I'm blowing my main fuse as soon as I start it. Could this be something I did wrong when I replaced the rectifier? Someone steer me in the right direction, I'm all out of smart ideas.
The trip has long past. And I have been working through the connections as I have had time. I haven't thrown parts in with fingers crossed, I'm to cheep for that. The two parts I have replaced tested bad as I have worked my way threw the bike. If I'm forgetting to answer any questions my apologies, all the knowledgeable help of more then appreciated. Bike runs on points and has not been tampered with at all. All original parts until I have had this charging issue.
Unplugged the regulator and it didn't blow.You need to isolate parts of the loads on the bike as a test.
Start with a fully charged battery.
Test #1; Unplug the regulator and then start the engine and see if the 20 amp fuse no longer blows.
if the fuse blows, replace with a new fuse, plug the regulator back in and try test #2
Test #2; Unplug the tail/brake light and leave it out. Start the engine and see if the 20 amp fuse blows.
