hey i just bought a 89 civic hatchback and there is a wiring problem...whenever i turn on the running lights, they turn on for like a second and then the fuse blows?

Do i have a short? and if so, what should i do to fix it?

Thanks

 

Do you have an aftermarket radio, if so I would start looking there

 

well my radio is aftermarket but i hard-wired the radio because the previous owner didnt have all the wiring in the car
