help with 2003 tracker
 

Hi I have a 2003 chevrolet tracker with now electrical power. I shorted out the 80 amp fuseable link while working on the vehicle, I replaced it the vehicle ran for a while with the check engine soon light on, after that did nothing. I have a good battery with 12 volts on both sides of the 80 amp fuseable link and on the starter terminal. There are spots for four more fuseable links inside the fuse box under the hood, there never was fuses there. Any ideas on what the problem could be? Thanks for the help.
