Dead Ducati

Looking for some thoughts / ideas please. A week or so ago my I noticed the battery tender on my Panigale 1199S (six plus years old with OEM battery) was flashing red. I turned on the ignition and the screen came on but upon pressing the starter, nothing. After a few tries you could see the battery was dying. I tried another battery tender and the same thing - started charging and in a few mins it showed bad. I assumed the battery was gone and after nearly 7 years with the OEM battery I thought it just needed replacing. I ordered an Antigravity lithium battery and put it in today. Other than some issues with fit I got it in, connected the cables and when I turned on the ignition I got absolutely nothing - the screen didn't come to life at all. Let alone start up. I borrowed a voltmeter and found that I had 13.6 V on the lithium battery and it stayed at this voltage when I turned the ignition on. It didn't drop at all. I then checked the OEM battery and it still had 12.4V so now I'm not sure if it was a battery issue after all? The last time I rode the bike it was a few weeks ago and everything was normal and when I got back from the ride I put the bike on the battery tender. I went to ride the bike again a week or so ago I got the flat battery (or so I thought) issue. Anyone got any ideas? Thanks in advance.

Any tripped fuses?

Long shot - Did you perhaps accidentally swap the polarity when you installed the battery?

12.4 on the old battery won't start the bike. Probably drops as soon as a load is put on it. Double check your connections on the new battery.

Thanks for all the thoughts and suggestions. Checked leads, connections and all fuses and all seem solid with no blown fuses. I haven't got the electrical skills to figure out a potential rectifier problem so I guess a trip to the dealer is next!!

Did you ensure the Li battery was fully charged before installation? They operate a bit different from lead-acid batteries. See the link below.

Thanks I've reached out to Antigravity to ask them about this as the instructions with the battery says its ready to use straight out of the box. I also measured 13.6V and it says it goes into S/D mode to provide one last charge when needed at 12.6V so I assume it should easily start or at least get the dash to light up at 13.6V. Appreciate the feedback.

right now i have a cheapo lead acid battery in my bike....hooked up to the tender for the winter. why, because my shorai is acting up....again. just keep taking advantage of the warranty i guess because mine seems to work once or twice and then it goes flat suddenly you don't even get the clicking. it's almost like i need to keep it on the charger when the bike is not running. so thanks for starting this thread, reminds me i need to send mine in again so i don't have to worry about it this summer. it's hard to leave the bike parked for long periods when away from home not knowing if it will start up when i return to it.

jump the thing and see what you have, had no issues switching to a Li battery

Main Fuse is also ok?

OK my dumb question for the day - where is the main fuse? I checked ALL fuses in the two fuse boxes that sit above the battery. If main fuse is not there I did not check it and don't know where it is. Thanks,

Okay, so I read through all the comments again.
As I see it:
- The original battery did light up the dash, but had difficulty with starting.
- New battery fitted with 13.6V.
- Bike completely dead.

The issue cannot be the new battery (should at least light up).
The problem must have come up during install.

Did you do any other work on the bike while you swapped the battery?
Parhaps one of the plugs somewhere on the loom, or at the dash itself pulled out?

Yes, that's all correct and I think I'm with you that something else has happened during the install - its not battery related. My problem is that my electrical knowledge isn't great and so I don't know how to check for a short. I think I need to get it to the dealer

Unless it is the main fuse which I don't know where that's located if it's outside of the fuse boxes above the battery?

I’ll remove my bikes covers in the morning and have a look...

Did you do any other work at the time?

No I didn't do any other work.

But thinking back when I first installed the new battery the positive terminal touched a couple of the positive wires and there was an electrical sound that came from the bike. Then there was nothing? I wonder if this caused something to short or trip? The noise was not the noise you get when turning the ignition on and the bike cycles through its start process.

I think you found your problem.

You can try to "˜reset' the CAN Bus, perhaps that will work. - Remove the + and - leads from the battery and remove the battery out of the way. Touch all the + and - leads to each other and keep them together for several seconds (>10s). (Keep them well clear of the battery while you do this).
Carefully re-install the battery and connect.

If this does not help, I think you perhaps fried something. The primary ignition relay has been a source of similar symptoms before.

If the reset does not work, I'd suggest a trip to the dealer.

I think the same, I guess you fried something
Because there is really no life at all, I hope it is only the primary ignition relay
I've got a friend who fried his ECU... but more expensive... was a 996

Tried the reset and nothing so off to the dealer I guess
Appreciate your help.

Please keep us updated on the outcome
