Dead battery after sitting for two days

[THRASHED]

This is a 2012 that I bought used.  I have no idea how old the battery is as there are no markings on it, contrary to what every page on the internet says there should be...DOH!  The battery is a Die Hard Gold.  This is not the first time it has gone completely dead.  After the first time, I have left it on the tender when parked at home.  I rode the bike Friday and I plugged it in when I got home (bad connection? possibly). Went to ride it Monday and all that came on was the ABS light.  Wouldn't even try to turn over.  I plugged it back in to the tender.  Tuesday morning, no issues. Battery is fine, 12.85V and the bike started right up.  I decided to take it to the shop to have it load tested.  They set the meter to 310CCA and it showed the battery is fine.  When I got home, I did a draw test.  I got 1.42 amps drawing with the key off.  From what I've read, this doesn't seem excessive. 
  I guess my questions are: Does the test really mean it's fine?  I don't have an issue doling out some $$ for a new battery, but I want to make sure it's necessary. And, is the amp draw excessive?

This sounds very much like it may be the early version of Audio Software
for the US & Canadian market ( having XM Radio ) that had a "bug"
which intermittently prevented the audio system from shutting down
when the Ignition is switched off, causing the main battery to drain !

This problem was resolved by Triumph several years ago, around November 2014 or earlier,
when they released an update of the Software from Version 1.04A to 1.04E, at no cost.

You can check which version you have :

The Radio must first be switched off, so :

Turn the Ignition ON, and if the Radio is ON, turn the Volume down,
keep going past "MUTE" to "OFF", then turn the Ignition OFF.

Wait a minute until everything has shut down,
then turn the Ignition ON ( don't start the engine ).
and wait for the Instruments to complete their sweep.

Press and hold the "P" Button until the "Diagnostics" screen is displayed.
If the Software version isn't displayed, use the Scroll button until it is.

If the software version is shown as Version 1.04A then this is the problem,
and you should get this updated as soon as possible to Version 1.04E.
( Ignore the second line displaying the "BB" Software version ).

Unfortunately this Software is only officially available from an authorised Triumph Dealership,
using their "TOL" system ( Triumph On Line ), and sadly many Dealers seem to be totally unaware of it !

This Topic explains where the Dealer can access the Software .....

Where Triumph dealers can find audio software updates (U.S.)

If your Dealer tries to Bill you for this update, then IF you have had your Trophy serviced
at a Triumph Dealership since November 2014, you could point out
that they are supposed to check for any Software updates at each Service,
and would appear not to have done so !

Also, if you have Version 1.04A I woukld recommend pulling the Audio system Fuse
until you get it updated, to prevent any further batteries from being drained.
( On my  Trophy it's Fuse No.3 ( 10A ) of the forward Fusebox
behind the Left Side Panel - the one with the little Music note symbol. )

If the Main Battery is drained excessively it may not be possible to recover it,
and could need it to be replaced with ( another ) New battery !

If you do need the software update and encounter any problems getting it,
send me a Private Message and I will provide further information.

Thanks for that.  I'll check this out today.  I suppose, in lieu of getting the update, I could just leave the fuse out?  I have a Sena system for my helmet and never use the radio on the bike.

If you have the “old” software version that will explain
why your battery keeps draining, so you could leave the Fuse out,
taking note that the Cockpit storage box Accessory socket
and the USB socket are also both powered from the same fuse.

1.03A . Well, that's one down. I think I'll pull a couple of fuses and see if the draw drops dramatically.

I can almost guarantee that Version 1.03A ( or 1.04A ) is the problem !

I find it amazing that it took nearly 8 years for the needed audio unit firmware patch to reveal itself.

When Triumph do "intermittent" they do a fantastic job !
