USB and battery drain

[H2OSMRT]

So over the past couple of months I have twice left a USB flash drive plugged in after finishing a ride. Within a week I go to start the bike and I have a dead battery. Find it hard to believe the USB would be a hot wired connection. Anyone else experience this?

Hi H2OSMRT,

I've not heard of a USB device left plugged in causing the battery to drain,
but there is a very well documented problem with earlier versions of the Audio Software
installed on US & Canadian market export models, which resulted in the Audio module not powering down
when the Ignition was switched off, causing the main battery to drain.

You can easily check the Audio software version of your Trophy :

With the Ignition ON ( but don't start the engine ) and the Radio turned OFF
( Volume all the way down to Minimum, Mute and Off ),
Press and hold the "P" button until the "DIAGNOSTICS" menu is displayed.
Scroll to the S/W VERSION item, and press Select.

The Latest Version for US market is 1.04E -  you have anything earlier ( such as 1.04A )
then get your Dealer to update it to the latest version as this is most likely to be the cause of your problem.

There are numerous Topics about this within the Forum -
just use the Search button and enter "Audio Software".

Let us know how you get on ! 

Cheers

I wonder if the original problem was that if there is a music source in the usb slot it keeps the radio on.  Which is why some people got it and others didn't

For  my two cents worth of advice: I've had a memory stick plugged in since day one (March 2013), and to this day never had any problem of drained battery. I'm not an expert but I would assume your problem is coming from another source.

FYI, I've had the dead battery problem (it happened twice and is now repaired with the software upgrade to version 104E) and my TTSE has never had a memory stick plugged into the USB port.  So, the problem lies elsewhere and is easily repaired with the software update.  I did my own,thanks to another member of this forum supplying me with the software.
I still have the file, so if anyone would like it, just PM me and I will pass it on to you by return email.  It comes with simple, easy-to-follow instructions and only takes a few minutes to complete.

My 2014 (serial # 62xxx) had the earlier software and the dead battery syndrome. I had no memory stick installed. The updated software was installed and I've never had a problem since, almost 2 years now, same battery as well.

Thanks everyone for you comments. I did check which version I have (thanks for the step by step Coconut!) And it is the current (104e). I had the bike sit for up to 3 weeks before with no issues but only when I left the USB plugged in. Guess I'll need to be more vigilant in remembering to take it out but will continue to see what the problem may be. It's a 2015 with 6500 miles (new in July 2016) so I'll have my 10k service in a few months and see if they can find anything.

I also have had a usb stick in my '13 TTSE since I got it, no issues, but I did have the audio software issue, since the audio software upgrade I've had no problems...

It's really easy to do yourself, if your dealer seems clueless, as some have been reported to be, might want to do it yourself.
