Thanks for posting it. And thanks for saying out loud what I think a few of us have realized is the truth.
Second 12 volt Lithium battery dead
21 - 32 of 32 Posts
for the moment 2 times per months without riding,anyway the charger Optimate Lithium LFP 4S 0.8 Amp is stopping automaticaly the charge when ok and switching to survey cycles mode.
Now I'm riding approx 80 km/week, today 13,11 V so ok. My pronostic is one time per month. I will survey the voltage if I note a decrease before pluging the charger.
I prefer to play like this rather then risking a definitive stop due to this small batt.
After this lesson learn I will perhaps adapt = 1 charge per month without riding and No charge if approx 250km per month.

Just posted on the main chat before I found this…. Just had her 1yr/1k service 3 weeks ago and dead as a door nail…. Worried about trickle charging the 12v battery as it so electronic versus my gas powered bike, will see what the dealer says after they fixed her after the battery died after only 300 miles (only clearly they didn’t fix her!). At £30k in the Uk it’s very disappointing and took six weeks to sort first time around. I even complained to H-D customer service… but they never even acknowledged the letter….. HD used to be very customer oriented, but sadly not so much these days!
Thanks for the post, interesting to know witch part they will change to fixe the problem. On my side, no 12V trouble, neither 12V specific charging durring this Summer+Automn. Voltage check today at 13V.
But after having reading your topic Il will operate a "prevent" 12V charging. bye.

Frank: were you able to get any more information on installing that Denali Soundbomb horn? I have the same model horn on my Livewire and I am now seeing that "12v Battery Weak" message some days. After reading your post, I am guessing that I made a mistake in wiring that horn directly to the battery. Would you have any more information on how to properly wire that horn, thanks in advance.
Hello Dave, no info from HD to add this direct acces for plugging a 12V battery maintenance charger. The logic usage is to never plug the main charger and my 12V charger at the same time .Only one 12V charge after this 3 months berfore riding. Never had 12V problem on my bike, it' s just a preventiv action after having reading all the 12V topics on the forum.

that did not address my question at all, but thanks
The Soundbomb was connected by the dealer to one of a few existing auxiliary connections that is available on the bike. They had the right HD connectors and harness extensions at the dealer. However, I am looking into a separate power source for the horn - separate from the the 12volt battery, that I would have to charge separately. As I may have noted before, the Soundbomb compressor has a 20amp draw and it trips the existing LW 15 amp accessory circuit if you blast more than 1 second at a time. You have to shut down the bike to reset the circuit. HD has not had any answers to how it can be connected to what would be a new and higher rated separate circuit. Its all a pain and the dealer has not been able to help at all. Very frustrating.

Frank: Please tell me more about your "2nd power source" idea. I disconnected my Soundbomb horn from my 12v battery, and my "12v Battery Weak" problem went away. I do have 2 extra of those tiny 12v batteries on hand (for another reason), do you think that wiring that horn to run on a 2nd 12v battery would be a good idea? and would you have any thoughts on where to mount that 2nd battery?
My thought is a second high powered lithium ion battery perhaps-like those used for jump starting cars or recharging laptops and iPads etc. I have not done adequate research on power or amps available yet. They are generally more compact and may fit under the seat. However, I believe they are smart batteries with managed power access etc and typically need to be “activated” or turned on and are not passively ready to go. In any case, I am thinking of a smaller independent battery with adequate power dedicated to the horn but I don’t want to constantly manage on and off. I will let you know if I make progress on this.
Having joined the club, a bit late, I’m now getting a low battery warning for the 12-volt battery as I’ve been unable to ride with ice and snow on the ground. Has anyone found a good workaround to this issue?
For what it’s worth, I’ve maintained a regular charging regiment. Adding 5% twice a week and maintaining the RESS between 30% and 70% per HD recommendations. The warning followed this. And after a long ride today, the warning went away.
I believe Harley Davidson printed a lie stating the RESS manages the 12-volt. It does no such thing. Only when you ride the bike does it seem to be charged. Not while level 1 charging. As an engineer myself, I find this whole situation unethical on Harley Davidson’s part, and more deplorable HD hasn’t recalled this.
If they don’t resolve this, this is possibly my last Harley.
