I parked my 07 mazda 3 a couple weeks back because i went on vacation. I just got back, and when i turn the key i got NOTHING. Engine doesnt even attempt to start. No clicking, no turning of the engine, NOTHING.. I decided to check my my lights to make sure they were all turned off, which they were. And when i put my charger on it to boost it, I get a repeated clicking noise.. The charger is also indicating that the battery is good and ready to start...

Anybody ever have this issue.. The car is a year old.

 

Sounds like corroded battery connections/terminals. Turn the headlights on and stand in front of the car. Have someone else try starting the car. When they turn the key, do the lights dim or stay bright? If they dim, it's in your battery connections, if they stay bright you have a bad starter.

 

This has happened to me in my previous car, apparently, a rat or some other small animal jumped into the warm engine and disconnected a wire clip or chewed a wire.
