O/T - Seeking some help for a dead Ducati
 

Sorry to go a little O/T but would like to utilize the knowledge of this forum for an issue I'm having with my Ducati.
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.

Check the kill switch on the right grip. Sometimes mine just needs to exercised a few times. The other is to remove, clean with a wire brush then re-tighten the battery cable connections at both ends of each cable. Good luck.

Maybe you should try a another new yuasa battery for comparison. I had some unusual behavior on my running/starting monster. Changed to a new yuasa and the issue was fixed.

Sounds like the typical Ducati Rectifier issue...this has been happening for at least the past ten years that I know of. Google it and you will become highly educated in it very quickly.

Thanks all for your help/thoughts. I've tried all the suggestions and still dead. I'm ok with the mechanical stuff but electrical is a bit of a mystery to me so I cant figure out if there's a rectifier issue or not. I'm also not sure how to figure out if there's a short somewhere. I guess a trip to the dealer is needed!!

Yep, I did double check that as well. That could have been a real rookie mistake so I checked myself several times!!
