I measured my "cigar socket / outlet" with a multimeter. Instead of 12v it had 19v. Is this normal? Is it my voltage regulator, alternator, battery that has problems?
Car: Peugeot 307, 2.0 XSI 2003 The 12v "cigar socket / outlet" is off when my key is turned off, and on when I turn it on.
Additional information: Battery is almost 1 month old. Mechanic replaced it.
