Okay, now get a voltmeter and measure the voltage across the battery.

If you read 13V across the battery, BUT you only see 8V on the dashboard
meter, there is a bad connection somewhere.

If you read 8V across the battery as well, then the battery is dead.
Put the battery on a charger.  Does it read properly after a few hours
on the charger?

If it does not read properly after a few hours on the charger, the battery
is bad and should be replaced.  THEN you need to figure out why it went
bad, since it's pretty new.

If it DOES read properly after a few hours on the charger, and the car
starts with the battery charged, THEN you definitely have an alternator
related issue.

Before doing ANYTHING you need to take the first step and read the battery
voltage with a voltmeter.  The voltmeter is the most fundamental piece of
test equipment available.  It's what cavemen used to debug fire with.  The
voltmeter is your friend.

Then...that says your battery doesn't have enough electrical energy to
engage the starter motor and turn the flywheel ( which is connected to
the crankshaft by a moving gear ).  8 volts indicates a discharged
battery.

So...that means the vehicle will _never_ start unless you have a
battery voltage of at least 12.2 volts.  There just isn't enough power
there to start the engine.

That could have been caused by a defective alternator not recharging
the battery.  BUT, you can try to charge it with a plug-in car battery
charger or a Jump Start from another vehicle.

Once your engine is running from a Jump Start, if it starts, then your
alternator is suspect.

IF your engine won't start with a Jump Vehicle and battery cables,
then you probably have a defective starter motor.

So the problem is either the alternator, the starter motor, or both.

Right now...we need a fully charged battery on your car to see if it
starts with that.  If it doesn't...your starter motor/solenoid is
suspect.  That clicking noise is the throw-out solenoid of the starter
motor -trying- to engage the flywheel, but there isn't enough
voltage/amps/power to get it to do that.

2 ways to try to get this engine running:
a) fully charge the battery in your car with a plug in battery charger
b) try a jump from another car using jumper cables, with the other car
reving its engine at about 1000 or more revolutions/minute ( fast idle
).

If both of the above fail to start the engine, the problem is
definitely related to your starter motor.

If the engine starts, measure the voltage again at the battery
terminals while the engine is running, and if you read ABOVE 14 volts
with the engine running, after the jumper cables are pulled off and
the car is *on its own,* then your alternator is GOOD.  Below 14 volts
and your alternator is not doing what it is supposed to do.
