yes i think i shorted it "i am stupid" i smelled something but i think that the power has protection in it because when i connect the it goes down the value on the screen of the volt to 0
I would expect a bench supply like that to have current limiting built in, and you usually set the current limit by shorting out the supply and adjust the current control until you get the current you want.
the clicking sounds like 'tap switching relays' - these select different taps on the power transformer, based on the output voltage of the supply, this reduces the power dissipation in the regulator, so for example if the output voltage is, say 5 Volts (either because this is the voltage you have selected, or because the Constant current/current limit mode has kicked in) then rather than powering the regulator off the 30 Volt tap, the tap selector would switch down to a 12 Volt or maybe a 6Volt tap (depends on the supply).
so it might be that a higher voltage tap on the supply is open circuit, and so when the supply tries switching up it fails?
do you have any brand name or model number on teh supply?
