First of all sorry for my english ..im a french guys from quebec canada

Hi so im new in this world and im learning fast as i can 😂 so heres my problem i just install a electric water pump and try to let te motor run till the thermostat open. After it did i check the fan on the radiator and noting was turning so i check both wire that go to the fan and both wire seem to be grounded ... i plug the fan to the battery straight and the fan start spining . So what should i check first cause its a 350 tpi in it so im confuse on what to check

That sounds normal.
Generally, the cooling fan usually is set to come on at a higher temperature than the thermostat setting (195°F ?).
If the temperature gets several degrees higher (say 230°F ?) than the thermostat setting, the fan should come on.

But both wire to the fan is grounded ( tested with a test light and both light up when i plug the test light on positive pole )

The black wire should be grounded, the black/red should go to the cooling fan relay.

Could that be a bad relay ? I disconnected rhe relay yesterday and both wire still grounded
