OVP relay?

i found this relay by the battery the other day and checked the fuse and it was blown.. so i replaced it with a 20A (all i had at the time) and it blew soon as i plugged it in with the car not running.. what all does this relay do? i need help bad. the car im pretty sure was jump started before with a 24v jump starter because everything that would be on with the key had the fuses blown to it. it runs but the idle is about 498 or 500rpms.. i was looking for a computer fuse or something and that was all i found that had a blown fuse. can anybody help me?

It basically supplies voltage to several systems and modules, and adds protection to overvoltage issues. I would say either A: you have a short somewhere in the vehicle, or B: you simply have a bad OVP relay.
