ABSTRACT A short circuit has been a source of problems to the electrical components experienced by electrical technicians and engineers during the assembling of the evaluable components on the board. I have managed to come up with short circuit tester which will automatically detect and indicate the short circuit available in the assembled board. The main aim of coming with this project is to reduce the loss of life of people when short circuit occurs, maintain the life span of valuable components installed in the board and facilitate easy way of troubleshooting the component effect during the repair damaged equipment. The two NPN transistor BC547 is used in the project design to since the presence of short circuit in the electrical circuit. The designed buzzer will automatically have signaled hence turning on Red LED when there is Short circuit in the circuit under the tester thus creating awareness.
