i have a 2005 Volvo XC90 and the other day I came home from work and it ran fine the next morning I went to go start it and there’s nothing I can turn the key to position 3 and get the car to crank but will not start and if I take my hand off of the key it continues to crank the battery is brand new I read the codes that are being thrown and I’m getting p0563 system voltage high and p0561 system voltage unstable checked all the connections and they aren’t loose and the alternator was put in just before I bought it please this is my families only vehicle
