Help Needed: Battery Drained. Again

[nb101]

I bought my 2015 TTSE around April.  Picked it up in Austin and rode it home to Houston. On my way home, I noticed for the first time the “Low Voltage Radio Off” message. Thinking this meant that my battery was old, I bought and installed a new battery.

Life was good.

One day, after a couple of weeks of not riding the bike due to business travel, I tried to turn it on, only to discover that my new battery was totally dead. Took the bike to the mechanic, who told me that that was normal for this bike and that I had to keep it on a trickle charger. So, I’ve been keeping my beloved on a trickle charger ever since.

Life was good.

This Sunday, discovered that my battery, although connected to the charger, was totally dead (and the charger has the red light/bad battery indicator on).

I‘m looking for advice on how to proceed

Well, from the other side of the world. I "think" you scored a bad battery. At that by far the most likely scenario is that if you replace this large paperweight, with a new high quality battery, you will likely never have another problem. I've left mine sitting for a fortnight (We ride all year round here) and it jumped to life afterwards.

The only other possible, but highly unlikely scenario which springs to mind is that there is a drain on the battery which exceeds the output of the charger. To check for this, change it for a known good battery, connect up the negative terminal, then set a multimeter on to a 10amp current reading and place one probe on the positive terminal of the battery and the other probe on the positive battery lead Including any accessory wires which normally go the positive terminal of the battery. Carefully read how much current us being drawn and let us know. Preferably it should be less than 0.06 amps.

Do you have an alarm or after-market accessories on the bike?

Thanks, teef.au.

To clarify, this is the second battery to go bad, which is why I'm thinking it's not the battery.

And there are no aftermarket accessories installed, other than the trickle charger leads, and the OEM top-case with a non-working power outlet.

This is a well-known and documented problem with the as-delivered audio system software on Trophy's with the XM satellite radio system (which means all bikes shipped to the North American market).

Your bike, as my '15 model was, was shipped with software version 1.04A, what you need to do is have the dealer update the software to version 1.04E. This will stop the constant drain on your battery which was causing it to go dead. Mine was totally drained after only five days of inactivity.

Thank you, bespoke.

I thought this was fixed for the '15 model and that they already came with the latest version 

I guess what confuses/worries me the most is the fact that this time the battery died WHILE being connected to the charger

You can easily check which version of Audio Software is installed :

Turn the Ignition ON ( but don't start the engine ) and switch the Radio OFF
( Volume all the way down to Minimum, Mute and Off ).
Turn the Ignition OFF, wait for everything to shut down, then turn it ON again
without starting the engine.
Press and hold the "P" button until the "DIAGNOSTICS" menu is displayed.
Scroll to the S/W VERSION item, and press Select.

As mentioned below you probably have Version 1.04A - you NEED Version 1.04E

Depending on when your Trophy was last worked on by a Triumph Dealership,
when they are supposed to check for and install ANY available Updates,
you may have a case to claim the cost of a replacement battery / batteries from Triumph,
as you could argue they failed to carry out the Update - causing your batteries to fail.

The Software Update has been available since AT LEAST November 2014 !

Cheers

Thank you, coconut!

I've just ordered a new battery, which should arrive on Saturday. Once installed, I'll be able to check the software version.

Will report back

My bet is on the audio software.  Mine has been parked in the garage for as many as 3 weeks occasionally( ), and never was even the least bit slow to turn over and start.  That was NOT the case before it had the audio software update back in early 2015 when I discovered on this forum what the likely issue was.
