Came with the bike goes direct to battery by the looks so I’m guessing possibly a battery charger tender? Anyone any opinions Thanks
if you peel back the rubber and inspect closely you should find a random code and a manufacturer, stick that into google ,theres a few different set ups you can either by the female bit that plugs on and attach to a charger or just replace both bits, i did it once and had to redo, solidly soldering and putting shrink wrap on to make it solid,
