Need help
Rode my bike home from worth Friday and it died, started it back up and it got me to the commissary leaving the commissary it died again and wouldn’t start the lights seizured like the battery was dead. Got it home after charging the battery and it died on the way home. Started it again and got it home. Tested the stator and it reads a little above 30v ac at idle. Put leads on battery and started bike to test voltage reg and at idle it barely stayed above 12v and would got above 13.6 over 2k rpms. Is it my voltage regulator? I wanna make sure before I go buying parts. It’s a 2016 Harley Davidson 48 model 1200

1. How old is the battery?
2. Take the battery out and get it load tested at your local auto store.
3. Sounds like the charging system is okay, but will not know until you get the battery load tested and see how many CCA and life of the battery it has.
4. Check all your battery cable connections at both ends and ensure they are tight and no corrosion.
NOTE:
The above information, while credible, is worth what you paid for it and should not be considered gospel.
Do due diligence, research and have a H-D Field Service Manual before working on your bike.
You will probably have many opinions and suggestions presented; make sure you research the person providing the helpful information as there are some who provide good information and some who speak out of other orifices with gibberish. You will figure out this quickly.

1. Okay, it could well be your voltage regulator.
2. Any modifications in lighting or power usage to the bike?
3. Should be getting 14 vdc or so when RPM is above 1500.
4. Perform check as linked below for stator & regulator.
5. You need to check the stator pin to pin to see if it is good in addition to seeing how much voltage (AC) it is putting out.
6. You also need to check the regulator while it is unplugged to make sure the diodes are good.
Did not Harley test the other functions of the charging system and battery? 9 CCA is not good. Even a new battery can go bad, i.e., shorted plate. Is the battery a known brand or some unknown aftermarket.
Charge the battery out of the bike, then take a voltage reading, should be above 12.7 vdc. Let battery sit on the bench for 6 hours and take another reading, should still be holding at above 12.7 vdc or so. If there is a significant drop in voltage, the battery is bad.

when I brought it to Harley to be tested after the bike died, it was at 9cca which is why I started testing stator and regulator

I don’t think it’s the VR if your charging at 13.4 to 13.6 on a fully charged battery that’s normal. It’s the same on a car/truck.
What voltage should my Harley be charging at?
Note: if your meter is reading anywhere at or above 13 volts you are in great shape. Remember, your Harley is a 12-volt system, so just above that means it can keep up. 13 volts is the point where the battery is not discharging with all your accessories on.
