    @Mikey Mike On my old GS,

    1. iPhone Plugged in
    2. Sargent Seat on High
    3. InReach Plugged in
    4. heated grips on

    As soon as I went high beam (which means 2 Erica + 2 Darla), I'd notice the voltage indicator on the NAV VI drop from 14.2 to 13.9 but it'd then stay there. Usually, it'd stay at 14.2

    I'm adding a Dashcam, Upgrading one Erica to Sevina and a Denali Soundbomb...which if all works correctly, the sound bomb will draw 15 amps and all of the clear water lights will strobe and then my alternator will explode.

    If ever you get stuck or confused you can always visit your local Ohm Depot :)

    I think @AdamChandler bigger problem would be him honking his horn with all that stuff and summoning an alien mothership thinking he was looking for a ride. Hahahah

    Your voltage dropped to 13.9 because your alternator had maxed out. You need to reduce the current load. 13.9 wont fully charge your battery.

    How do you arrive at this conclusion?

    That's why I mentioned it. I'm not a battery expert but now we're adding one Sevina light and a dash cam so I am truly concerned about maxing out the alternator (stator?) I think I have a 650 watt ceiling. Lights will occupy about 200 of that, I assume bike around 150 of that? I didn't think I was anywhere close to maximum draw.

    IIRC the generator( alternator) output is 510 watts.. I could be wrong of course...

    Looks like 510. I was thinking the oil-head stator was higher and it seems it was.

    Erica - 60 Watts
    Billy - 10?
    Darla - 24 (x 2 for 48 watts)
    Sevina - 70
    Sargent Seat - 23 watts
    Dashcam - 25?
    20-40 watts extra for charging iPhone, InReach, PowerLet

    = 276 watts

    Before the normal 150-200 for bike functions so I think I'm still under the ceiling.

    Yes the Oilheads had more oomph in the electrical dept... You should be fine on your power draw but do keep and eye :umph on the voltage meter when you run all or most of your stuff.

    As an airhead owner, I never thought I'd find myself saying this with modern BMW's. Have you considered a higher output alternator? Is there one even made? Perhaps something along these lines?

    I have the bike completely apart right now. If there's an upgraded LC Alternator around 5,000 watts, let me know.

    The function of the voltage regulator (VR) is to regulate rotor output current such that the voltage at the battery is held at a pre-determined, temperature-compensated voltage (regulating voltage goes down as temperature goes up). When the current load on the alternator exceeds the current output ability of the alternator, the voltage at the battery starts to drop.

    When you see the voltage drop, try increasing the RPM to 2500-3000, it can put out some more current at higher RPM. That may allow the alternator to put out a bit more current. Basically, though your measurements are telling you that you're near the alternator's limit.

    Its your right wrist "pin it to win it" WFO! :ricky Hahah. That being said the stock battery is very weak for these bikes in anything cold weather the stock factory battery struggles to turn it over. Probably because they are using a battery that needs a styrofoam base taking up an extra inch in the battery tray.
    Yuasa GYZ16H 240CCA battery will fit perfect with the styro removed, if and when you replace the stocker.

    Add on a “continuum transfunctioner” while your at it.

    Yep...that's one thing on my LC that has stuck in my craw...my "ancient," supposedly less evolved '05 GS had 720 Watts iirc. Wtf is with a 30% reduction on newer bikes ...you know, with INCREASED electronics generally managing and adjusting critical riding features on the fly?

    Eta: just thought about that as I posted...possibly self-contained answer there: less FREE watts available to accessories, BECAUSE the bike requires more on an ongoing basis?

    what I was reading was no more ABS Servo which saved 150 watts. when the LC dropped this, it didn't need the stator to be putting out 720.
