2009 CTS4 2007 STS
Could anyone tell me what is the correct voltage 0n a 97 STS. Last night had to get a boost because my battery just all of a sudden died on me. For the last couple of days I've had the sentinel lights set on max so my wife can have enough time to get in the house but the car was cranking fine. Before the jump the voltage was around 8 now it never gets past 13.8 and goes as low as 13 while i'm driving the car. Also when I cut the car off now the radio goes off and comes back on and all of the info on the DIC is reset. The car cranks fine but that makes me think there is a shortage since I boosted the car. BTW all cables are tight and free of corosion.
