Last week our DTS started running rough, you could feel it in the idle as well as driving, just before turning it off the check
charging system light came on. A day later my wife went to start it, all lights came on but it wouldn't start. I wasn't able to
look at it until today and it is completely dead. It won't even let me turn the key back far enough to remove the key.
My wife just told me that a couple of days prior to this happening when she would start it the windows wouldn't work unless
she turned off the car and restarted. Obviously I will start with the battery but it is fairly new, then to the alternator. Would
a dying alternator cause it to run rough. Just thinking to myself. Any suggestions?
So I charged the battery, the car started up fine with the check charging system light on, next I disconnected the battery as the car was running and it shut off instantly. In my mind that tells me the alternator is gone. Before I start to remove the
alternator is there any other diagnosis I should look in to?
