The inbuilt battery charger let go of the magic smoke so I threw it out because it was beyond economic repair. There are three wires for the new portable charger to plug into, Red positive, Black negative and Green ground, I've got the Red and Black sorted but I was wondering where the ground would be, would it be the chassis? I don't want to risk frying any of the microprocessors on this thing by experimenting. Any help will be appreciated.
