I replaced the battery yesterday. One of the bid fuses is making a clicking noise. The old battery let out battery acid. Nothing is working juat a dim light when the car is open and a clicking noise.

Did you make sure the connections were very clean and tight? The POS (Red wire) sometimes gets acid between the connection. That can make the battery not start the car. Clean that connection and put a small dab of Vaseline on the mating surface to prevent oxidation ... make sure it's tight

check your connections, and if the cables have any green in the they should be changed, This causes resistance ,you have a bad connection there somewhere that's why a relay keeps clicking on and off
