I bought a Deltran Battery Tender Jr. for my '05 620. I went to install the pigtail to my battery just a few minutes ago and discovered one already attached. It looks EXACTLY the same as the Deltran's that I just bought and even has the same fuse number and markings on the fuse holder. Is this a factory pigtail for the Ducati trickle charger or is it a Deltran that perhaps the previous ownder installed? Can I safely use this one for the Battery Tender Jr. that I just bought or is that not a good idea? Not that it's a big to change out the pigtail but it's already routed neatly down the frame and I'd rather not swap it out if I don't have to.
use it, you're fine
most dealers install them for customers before the bikes on the floor
