[QUOTE="oscar, post: 168873, member: 2757"] 13 volts with the ignition off ? it should be around 12.6 / 12.7 ( 6 cells in the battery, 2.1'ish volts per cell ) what i'd do is check that your voltage regulator on your alternator is operating correctly. multimeter on the battery with the engine running, voltage regulation output should be in the lower end of 14 volts. overcharging is just as bad as undercharging, when the alternator overcharges it will automatically cut the ignition and switch the engine off to protect itself ... even if you are cutting along at 70 on the motorway lol :) this will be the ECU either having a typical britney spears style breakdown (britney spears fan? deal with it!) or the ECU protecting itself to prevent critical damage. pretty sure it won't be anything major though [/QUOTE]
