1990 Jeep Cherokee Laredo Electrical Problems

I replaced the fog lights on my Jeep (the originals rusted through). The lights operated as they should for about 2 months. I had them on one evening and noticed my headlights went dim. When I turned the fog lights off the headlights regained their brightness. Later that night I turned the fog lights back on to see what was going on and smoke began to come from the driver side fog light. The insulation around the wire coming out of the fog light melted. I then disconnected the driver side fog light completely. I then turned the passenger side fog light on to see if it was still working. Smoke began to come from under the hood. I was able to trace its source to somewhere beneath or around the battery. Since then the following items cease to work (items I have found so far):

1.power door lock switches (both), 2.power seats (both), 3.fog light switch "power on " light (probably switch itself, fog lights are no longer connected), 4.rear defogger switch, 5.digital dashboard clock, and 6.headlight 45 sec delay automatic shutoff (normally available when headlights switched off after engine is turned off)

I have ruled out the 10 amp dome light fuse (dome light and radio still on). I pulled the two relays behind the passenger side kick plate and swapped them around without having any luck.

Any suggestions would be greatly appreciated.

Thanks

UPDATE:

5.The digital dashboard clock is working, but you can't change the time. 7.I found that the the engine compartment light under the hood isn't working. 8.The battery is being drained. I think there is a short circuit pulling power. The battery and alternator were fine before this incident.

I was able to find a fusible link that was bad. The wire is all mush. It attaches to the 2" DIA Cylinder thing between the battery and the relay center.

Thanks for the replies, Brett
