Hello! I have a HF car battery charger (model 46944) and the metal foot in the front bottom of the charger keeps coming off (now it's lost). Since the foot is metal I am assuming it is also a ground for the charger. Anyway, I am thinking about just getting an all metal caster and mounting it on the bottom front of the charger. Anyone know what's inside these chargers? Obviously I don't want to drill into anything I shouldn't, or ruin the machine. Any help here would be greatly appreciated! Thanks in advance.
