Bike is dead (battery)

[MidnightSE]

It's been a while since I've posted anything.
Up until recently, my Trophy hasn't given me any issues.
The bike had sat in the garage for almost 4 months due to my shoulder issues. The shoulder is still an issue, but not as bad as before. It is getting better. So I re-started riding.
During hibernation, my bike was plugged via battery tender.
It has started with a first push of the button, after its initial gauge prove-out
I'd enjoyed a day of riding. Parked it back in the garage. Made sure everything was off, like bar heaters and the seat (it was a 40-ish clear day when I'd ridden it).
A few days later, I wanted to ride it and found the bike completely dead. I hadn't plugged the tender, however.
I measured the battery at 6V. I plugged in the battery charger, restored the charge. However, the battery is an AGM, and it had failed a load test. I got a new battery.
After installation, and making sure charging is ok (14.3V at about 40A initial at idle) I've ridden the bike for a couple of weeks with no issues. Every time both bar and seat heaters were on. No issues starting the bike.
That it's up until today.
The battery is flat (5-6V) after sitting in a garage for just one (24-36hrs) day after an almost full day of riding with multiple restarts. 
I haven't had time to delve into the issues. But I'd found the SAE connector fuse blown.

I am a bit bewildered by this conundrum.

Thoughts???

Cheers...

You should check if there is a short circuit in the area corresponding to that fuse or some earth connection that causes the battery to discharge.

Stripped cables that are rubbing against the chassis or some defective component that consumes more amps than necessary.

Also check that the blown fuse is not of lower amperage than that corresponding to that connector.

Have you checked the much reported Audio Software problem ?

The early Version of the software ( Version 1.04A ) caused problems exactly like those you have had,
where the Audio Unit would intermittently fail to shut down when the Ignition was switched off,
causing power to continue being drawn from the battery, flattening it.

A software update was released ( Version 1.04E ) that fixed the problem.

This issue ONLY affected US / Canadian export Models with the XM Satellite Radio system.

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

• 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.
  
  
• Wait for the Instruments to finish their "sweep", then
  Press and hold the "P" button until the "DIAGNOSTICS" menu is displayed.
  
  
• Scroll to the S/W VERSION item, and press Select."i"
  
  

As mentioned above, if you have Version 1.04A - you NEED Version 1.04E

The update can only officially be performed by a Triumph Dealer.

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,
if you could argue they failed to carry out the Update - causing your batteries to fail.

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

if you DO have Version 1.04A, it is recommended that you remove the Fuse for the Audio system
when leaving the Trophy parked, to prevent the possibility of any further power drain.

( Forward Fusebox under the Left Side Panel - Fuse No.3 - 10A )

Let us know how you get on !

Dear Coconut,
You're a well of information.
I haven't had a chance to check until today.
You were right, I have old software.

This begs a question, if I keep radio of (manually) will it be disabled or still actively contribute to battery drainage?
Or, like you suggested, pull the fuse out.
I don't use radio , or any other built in features at all.
Cheers...

Safest to pull the audio fuse, and the next time it's at a dealer have them hook it up and update the satellite radio software.  Triumph should update it for free, and you can't do it yourself with Dealertool or Tigertool.  Should solve that issue, but you will still need to find the cause of the blown fuse.

I really don't know if there is any risk of the radio continuing to draw power
and drain the main battery when the radio is switched OFF, prior to having
the latest Version 1.04E software installed, but it would seem ( from the comments
of other Members ) that removing the fuse does eliminate the problem.

Note that removing the fuse will also disable the USB socket in the storage compartment,
that you might use for charging a Phone etc, and also the dedicated Sat Nav power socket.

I'm unsure which fuse you mean for the "SAE Connector" that was blown ?

Cheers 

[MidnightSE]

SAE connector is  a physically self-mating hermaphrodite two-conductor DC connector commonly used for solar and automotive applications (also motorcycles). And it is usually equipped with a fuse. 

I've pulled #3 Audio 10A fuse.
I keep my fingers crossed that it was the culprit.

OK, so presumably that SAE Connector / cable is used for your Battery Tender ?

Or is it something else ?

In your previous message you mention that the Battery drained without the Battery Tender being connected,
and we have now confirmed that you have the "old" Audio Software with the "bug" that can cause
the Battery to drain, so it's 99% certain that is the problem, and not the Tender.

With regards to the fuse blowing in the SAE Connector, if it is for the Battery Tender,
could it be that the Main Battery had drained so low, that it was beyond the capabilities
of the Battery Tender to restore it when plugged back in, and excess current
was pumped out from the Tender trying to restore it, causing the fuse to blow ?

In any event, I'd check the cable for any physical signs of damage to the insulation,
and / or poor or corroded connections etc.

Cheers
