charging sys help needed please please
Hi all,
A couple of weeks ago the engine and bat light came on on the ol lady's 06 road king. So I thought after 5 years the battery is toast so I checked it with a volt meter and it went from 12.7 to almost 14 vdc the bike needed tires so I took it into my guy and he checked the charging system and put a new battery in and left on a 4 day trip. Four days later were almost home and the bike quits and the battery is dead. So after swapping batterys and boosting one bike off the other we made it home.
So next day I charge up the battery fully and put it back in the road king and check it with a volt meter and did a milli volt drain test, clear the code and it's all good And it's 12.9 vdc so I check it in the morning and it's still 12.9. Yesterday she rides it to work and comes home and the bat and engine light are on and it's 12.7 and still 12.7 this morning.
So in a nutshell what I'm getting at is it's not draining, the battery is new and if the voltage goes up when it's running it's not likely to be the stator so I'm thinking maybe the regulator is not doing it's job when it heats up. Anyway tonight I'll check the stator and connections and go from there.
What do you all think. Had a similar experience.
Thanks

Seems to be on the list. I did hear back from the dealer asking me the same question so I told them look it up it should be on their system, we did buy 3 bike in 3 years so it should, duh. Anyway I'll wait and I'll get the vin tonight if I don't hear back. Also they show a part no for the reg I can check also. So thanks I'll let you know what transpires cuz it seems a lot of folks had the same problem.

PM'd you back. It doesn't show any open campaign history for the bike. That doesn't mean that your voltage regulator still didn't go south though.

So no recall. Over the last couple of days I checked the voltage at night and in the morning and the voltage doesn't change over night and also did a milliamp test. Yesterday after a 40 k ride the voltage went from 12.7 to 12.1 so no charge. My guy before the trip checked the chargeing system and I trust him fully and it would be pretty had to test the stator and misdiagnose a problem it's either good or not. I'm thinking that the charging system was tested when it was cold and when it gets hot the regulatore doesn't charge. The only hith to this is the 2 or 3 time I have checked the voltage when it's running it does come up 1.5 vdc or more so what do you all think.
