It as the 3 point I couldn't see from your pictures Blake, whether it was an original 2 point mounting unit or the replacement 3 point unit that broke?
I love the colour of your leather btw.

I figure the hd part number would be helpful! Sorry to hear you had the same fate. An addendum: I replaced the rectifier with the H-D version part number so generously supplied by Blake and all was well. There was a bit of fiddling to get it to work but all went well.
Now, when I start, there is a voltage of 12.8 to 13.0 on the battery at rest. When I am running it hits 14.5 to 14.6 volts. That means it is charging.
Add this to the list, as in:
When it breaks, and it will, replace with...

Interestingly MMC replaced my Rectifier at its service a few weeks ago - nothing was said - I just noticed that altho mine was a 3 point - it had been replaced. Am getting the same readings as Blake.

Yesterday I encountered the same problem. Fortunately I was alert to the possibility thanks to this thread and had the voltmeter punched up...I watched the voltage drop to into the elevens and was able to make it home. Because I have the special talent of fixing things that aren't broken, I wanted to test the output and health of the alternator before assuming the problem was the regulator/rectifier. Ironically, the most accessible info that I found was on the Cycle Electrics website, manufacturer of our dreaded CE-601 units. The misspelling is part of the correct URL: http://www.cycleelectricinc.com/Diegnosing%20Alternators.htmI checked an old automotive shop manual as backup, and it did seem safe to disconnect the 3-pin plug and run the engine. Before doing this, I had charged the battery to 100% capacity. I got 23-24 VAC on all three legs with the engine idling at 1200 rpm, and none were shorted to ground as indicated by my test light. This was a huge relief to me, because as you know, R&R of the alternator is an engine-out job and not something we in central Oregon (no dealers) like to contemplate. It was then a matter of handing over $150 at the Harley shop for the same unit that Blake put in. I have yet to enjoy the 'minor fiddling' referred to above but things could have been a lot worse. The 3-point mount appears to me to be very robust, but what is mounted to those cunning triangular plates is a Cycle Electrics CE-601 with two holes in it, which have been drilled out. One of the three rubber vibration isolators had cracked halfway through, but a spare from my Norton Commando stocks will fit with a fender washer as a shim. The output of my alternator, if my voltmeter is reporting accurately, sure seems robust... Steve Black

Sounds like another good fix Steve.

Went out to the 'car' this morning to find the battery completely flat , suspect I too have been caught by the dreaded rectifier problem. Have been using it every day except for last 3 or 4 ,so far it's always been showing a good charge going in. It originally had the 2 point mounting but was replaced by a 3 point one when at the factory in January.
Have put it on charge and had a word with Krazy Horse who will check it out when it goes in for its service on Tuesday.

Did somebody borrow it and leave the lights on without telling you?

That does seem a likely explanation, although not sure how they did it without a steering wheel! :-D
