  • Non-opaque junction box cover with troubleshooting electronic circuit board
    Patent number: 8764211
    Abstract: A non-opaque junction box cover and troubleshooting electronic circuit board are described. The circuit board has one or more light sources. At least one of the light sources is configured to emit light if power is present at a specific terminal stud within the junction box. The non-opaque junction box cover transmits this light, allowing one to troubleshoot a problem in a vehicle's electrical system without opening the junction box. In one embodiment, the circuit board has holes that align with the terminal studs in the junction box. The holes allow the circuit board to connect to the terminal studs physically and electrically without additional fasteners and wires. In another embodiment, the circuit board is coupled to the non-opaque junction box cover. Proper alignment between the non-opaque junction box cover and the circuit board ensure proper electrical contact between the circuit board and the terminal studs.
