Just to complement what @aayp wrote, do keep your battery charged. However, that does not mean it should be plugged-in all the time. AAMOF, I have actually toasted one battery from my PWC that way. What I do now is periodically top-up the charge then UN-plugging them for a few weeks & repeat thereafter. YMWV.
Just to confirm your experience of toasting a battery in your watercraft, was it a smart charger (ex.like a Battery Tender JR.) that did this? I keep many things in my shop plugged in (watercraft, motorcycles, garden tractor, summer car) with the device mentioned above 100% of the time when not in use and have never had an issue wrecking a battery...
Blown fuse....I went to connect a battery charging to my SAE adapter on the right side of the bike and to my surprise it didn't work. After spending time on the phone with tech support for NOCO chargers I had a plan ;-)
I checked the voltage and got 0v. So it looks like it was not connected. Is this common ? Am I missing something dumb ? (I hope so)
Re: the first item, this is the purpose of the decompressor in the Superquadro engine...My dealer told me the same and even pre-wired it with the battery tender ring terminal harness (which was nice of them). I think there are 2 reasons that Ducati is instructing their dealers to bring it to the owners attention.
Based on my previous Ducati ownership experiences it would appear that starting a big twin is more taxing on a battery than starting a similar size I-4. My 1098 was slow to start as was to a lesser extent my Hypermotard. The 1098 needed to be ridden all the time or kept on a tender.
By them mentioning it to the owners it reduces the warranty claims for bad batteries. With as few miles as some of these bikes will see on an annual basis it is quite possible for a battery to just to go bad within the warranty period. I bought a brand new leftover 2014 Honda CBR1000RR SP that had to have the battery replaced, it was "new" but wouldn't hold a charge.
