You guys are silly... (I love it !) 
. Thanks for the ideas but i had the battery tested , it has a full charge and i replaced the terminals 6 months ago when i bought the battery. The "click" is coming from the coil, or maybe a relay. Would either of those components click if its bad ?

The correct way is to bypass the ignition switch by jumping the switched terminal on the starter to the battery terminal on the starter. Not the battery hot lead to ground.

See the two large screw terminals on the starter solenoid? Short those two together with a screwdriver momentarily.
One terminal goes direct to battery +, the other to the starter motor. When you short them the starter should crank.
The third, smaller terminal is the "start" signal from the ignition switch. There should be 12 volts on on the wire connected there with the key set to 'start'. Unplug it to check to avoid accidents.

The clicking you're hearing is the starter relay. This magnetic relay shorts the two terminals you've been asked to short with a screwdriver. The voltage drops so low, because of the corroded battery terminals, it releases. Voltage rises, tries again. Click, click, click, as it tries to short the terminals.
Have someone turn the key, put your ear near the battery terminals, they'll sizzle.
Clean the battery terminals!!!
