This is actually a motor bike question but perhaps someone can help anyway.
I fitted a usb charger to my bike. It came with a long cable- two strands, a black and a red with an inline fuse fitted to the red. Each had a large ring terminal connection "clearly" intended to fit directly to the battery.
But it appears to drain the battery if the bike is left standing for a few days.
I obviously expected that when not in use the charger would not use current.
How likely is it that such a unit would have a small, constant drain?
