... 12.9! wow that's high. it should not be over 12.75... but when you turn on the key, the GP relay kicks on, dropping your voltage to around 10.6 then once you start the car, the relay should shut off, letting your alternator bring battery voltage back up. if the relay stays on, it'd take a big alternator to keep from discharging the battery.
