fusible link

I have a 1989 Jeep Wagoner Limited (XJ version basically a cherokee sport) that is having problems starting. I don't have any power at the ignition switch. I replaced the starter relay and a fusible link and reset the ECU. After resetting the ECU it started after 25 minutes. It started and ran...

Okay so dumb move on my part i put the wrong battery in to my jeep and tried to start it and BLAMO I hear a pop, and now there's NO power. The light bulb doesn't come on under the hood even when a good battery is hooked up. I have not power to anything won't click when I try and start no horn...
