    That's GOOD NEWS about your Low Voltage message.  :169:

    If the message clears after starting the bike, and you can then turn the Radio ON
    ( if you wanted to ! ) by pressing the Volume UP button, then all is good -
    it's just the system detecting low voltage as the Starter is cranking.

    Cheers  :821:

    Thank you Goodoni for your clarification.

    Of course, if you need help, we will be willing (whenever possible) to help you.
    Back to the subject TES...

    Check the TES module connector just below the right fairing cap. Take off the seat and the small cover, next to where you will find 4 relays on the left side, above the rear brake pedal.
    Only motorcyclists know why dogs stick their head out the car window.

    Just bought a 2015 trophy with approximately 9000 miles. Fourth time I go to ride it it doesn’t start. Audio off low voltage is the message. Bike won’t start at all. Last time I wrote it I kept waiting for the heated grips to engage but I think like many I have the button but not the grips. Can anyone please give me some pointers on what to do to get the bike started. The nearest triumph dealership is three hours away. Thank you guys

    Hi,

    It’s always difficult to diagnose remotely, especially with such limited information, but here goes !

    Most likely is a faulty / discharged battery or poor battery connection(s).

    Test the battery voltage and that the connections are clean and tight.

    The U.S. export model with XM satellite radio had a software bug
    that could leave the audio unit drawing power when the Ignition was switched off.

    See this Topic for details and how to check the software version installed on your Trophy :

    HOW TO: Obtain the XM Radio system Software update

    If the battery is definitely good, read the information in this Topic
    to help find what’s wrong - Scroll down the page to “ENGINE - WON’T START” :

    HOW TO: Check the most common faults and issues, Page 2 “E to O”

    If you still need help, reply with details of exactly what happens
    when you try to start the engine from turning the Ignition on, e.g. :

    Do the Instruments light up and the Speedo & Tachó dials complete their “sweep” when you turn the Ignition on ?

    If they don’t light up, try moving the handlebars from side to side - if the Instruments
    suddenly light up this is a sure indication of damaged Ignition Switch wiring,
    for which there was a worldwide Safety Recall issued. 
    See the Link in my signature line at the bottom of this message for details.

    Have you checked all the items of the Safety interlocks ? : 
    Engine Kill Switch set to Run, Gearbox in Neutral or Side stand UP if any Gear is selected,
    Clutch lever held IN when Starter button is pressed ?

    What happens when the Starter button is pressed ? -
    Are there any “clicks” heard either just forward of the Battery ( Starter solenoid ),
    or behind the left side panel ( Starter Relay ) ?

    Hope this helps - let us know how you get on !  :028:

    Mine does that too if I leave it sit for a few days(have other bikes) Put it on a battery tender and the light won't come on.

    ChiefMn :
    Put it on a battery tender and the light won't come on.

    What light ? I don't see any mention in this Topic of a light ?

    The most recent problem is where the Bike won't start and has an "AUDIO OFF LOW VOLTAGE" message,
    and now awaiting further clarification as to what the actual "symptoms" are.

    CajunTrophy :

    With regards to your Heated Handlebar Grips ( or lack of them ),
    these were not fitted as standard equipment, although the switch WAS !

    This resulted in many owners believing Heated Grips were fitted when they weren't,
    and that misbelief also extended to some Sales people who have been know to
    incorrectly advertise that Heated Grips were fitted when they weren't !

    Once you have managed to get the engine started, here is some more information for you :

    You can check if Heated Grips are fitted by looking underneath the Storage box under the left handlebar grip.
    Remove the visible Button Headed bolt ( 5mm Allen key )  from the rear edge of the box,
    Open the Lid ( Ignition ON to unlock ! ) and remove the similar bolt from inside the front of the box.
    Pull the storage box upwards and rearwards to release two "pegs" from their rubber grommet mountings.
    Turn the handlebars fully left and squeeze the clutch lever to allow the box to be lifted out.

    You won't need to release any of the wiring connectors attached to the storage box -
    You are looking in the area underneath it to see if Heated Grips are connected to
    the Wiring Harness Connector Sockets, as shown below ( No Heated Grips fitted ) :




    If Heated Grips ARE fitted then take note that they only work with the engine running,
    and will also be disabled if the ECU detects "Low Voltage" so that may be why they don't work ( if fitted ) !

    If they are NOT fitted and you want them, the complete Kits with the Wiring connector housings and Shorting Plug
    are no longer available from Triumph.  The individual Heated Grips are still available but not those other parts.

    There is a separate Topic however, for anyone needing those parts - which I can provide, here :

    HEATED GRIPS "Unobtainable" Parts For Sale !

    Cheers  :821:

    OK so I will check for the heated grips connections under the storage box on the left to ascertain if I have heated grips or not. I certainly appreciate that information. In the meantime today, I have charged the battery that was in the bike successfully according to the charger and still have the same result no start. So I switched out to a battery that was brand new and got the exact same result. All electronics seem to come on. The starter is engaged. It says if it’s flooded or has no power getting to the ignition. Of course I know it’s an EFI engine, so I continue to spin the starter – I’m simply not getting any fire to the pistons for it to start???

    OK, A couple more things to try - Open the Fuel cap and try again,
    in the unlikely event that the Breather hoses are blocked causing a "Vapour Lock".

    Since the last time you rode it, think if you have done any work on the bike,
    or taken anything apart that might have disturbed an electrical connection ?

    Check for any DTC's ( "Diagnostic Trouble Codes" as Triumph calls them ) = Fault Codes.

    This Topic explains how to do that, and download a list explaining what they mean :

    Servicing Data, Reference Info. & DTC ( Fault ) Codes

    Scroll to the message dated March 11, 2015, titled Diagnostic Trouble Codes ( DTC's ) / Fault Codes

    Another possibility is a blocked Fuel filter, but again unlikely.

    Further diagnosis will be difficult without the bike being hooked up to Diagnostics equipment,
    which Triumph Dealers have, although After market equipment is also available,
    such as DealerTool, though a certain amount of prior knowledge is needed,
    to determine whether any particular sensor readings are correct or not.
