Older Home Security System - blowing fuse
I have an old Radio Shack brand security system wired within my home. We had a power surge at my home that blew out my garage door sensors and killed the alarm system. I fixed the garage doors sensors with replacement boards but the alarm system continues to blow one of the internal 1.5 amp fuses (fuse for the 3 control pads in the home). I am not sure where to start, any ideas/suggestions?
