Thanks for remembering me.
The problem is in my B&D pilot the fuse is not to be seen, it is hidden inside the battery, because it comes with one option.
Either you get a new one you have to change the battery or forget it.
They are amazing they claim change the battery assembly, but the battery is fine.
