mobile phone charger
I want to convert a mobile charger from an old blackberry phone to be able to power my gps on the bike. My problem is I dont know which is the positive wire for the fuse attachemnt.
The power cable on the charger is a single cable with insulation. Inside the insulating sheath there is wire (obviously), this wire surrounds an inner insulated wire (Insulation white in colour, no stripes or any other colours).
Of those 2 wires, is the inner or outer wire the positive ?
Anyone ? - thanks
