Battery and alternator tested as fine but...?
Hey so two days ago I jump in my 2008 LX and it starts right up everything is great and I drove it around all day. Then yesterday morning I went to go start it and got some sounds like a dying battery. Tried to jump it and it still wouldn't start. Pulled the battery and had it tested, said I was getting 529 cca out of a 500 amp battery. So I figure it's not the battery and it's not the alternator because it's obviously charging the battery. I just put the battery back in, and now the dang thing won't even light up the dash or ding like it usually does when to key is inserted! Help please!
If you think a good mechanic is expensive, try hiring a bad one

Got a voltmeter?
While the key is on and the problem is present:
Got voltage at the battery posts?
Voltage on the cable ends?
Is the ground cable connection on the frame corroded?
If that's not it.....Google how to do a voltage drop test and diagnose it.
IF you jumped or connected the battery backwards, it blows the biggest main fuse immediately and the car is flat dead from that point on.
