Default 2004 Caddy CTS electrical problem

I have a problem with a 2004 cadilac CTS, it was in an head on accident and now I can not start the car. It appears there must be a short, as when I try to charge the battery, I can only get 11.4 volts into it and I can not even get the instrument pannel to light up. Only the door ajar alarm, and auto matic door locks work. I am unable to move the shifter out of park. Any Ideas???

If you cannot get at least 12.6 V into the battery then it needs to be replaced. That would be the first thing to do. When battery voltage drops too low on most vehicles the system will automatically turn off the headlights, reduce interior lighting, etc. in order to save power from the battery. That's what happened when my alternator went out

The low voltage being detected could also not allow certain switches and sensors to work. A sensor reads when the brake pedal is depressed so that you can only shift gearing when on the brakes. This prevents people from shifting out of D accidently and such

How bad was the head-on? It could have possibly damaged or un-screwed some crucial ground wiring which might prevent the starter from turning. Is the engine even turning over, or does it just make a "whirring" sound, etc.? There are a LOT of different things that could be wrong.

Hope this helps some......

Shouldve run a failsafe, or atleast a throttle return spring. Probably wouldve prevented that head on crash .
