I have a 2005 C5500 duramax. I had the key on checking out my new gps. The engine was not running. I saw the glow plug symbol come on and go off. I tried to start the engine, but nothing. I noticed my edge juice with attitude display was not working. Any ideas what could have happened?
Is there a breaker that could have tripped due to me leaving the key on but not starting the engine?

Thanks
