1998 Dodge Caravan Electrical system is down.

Ok. Full story. I had a cooling fan issue before and had installed a bypass switch to activate the radiator fans. I have since fixed the fan circuit and today decided to remove my bypass switch. Right after removing it my temp gauge in the dash and my scan gauge II read the engine was overheating at 260. I had to turn on the heater to get it back down to acceptable ranges. I look under the hood to find the fans were not working again and Im getting a P1491 code. Fan Relay Circuit Problem. I made it running the heater to my friends house a couple hours away and parked it. Right away replaced the relay and one fan will come on only. Also, noticed that all the lights were pulsing (dim to bright) along with the engine idle which seemed to go up and down slightly. A high pitched noise appeared to be the fuel pump also pulsing with the engine. The engine did bog out and stall once. After it stalled out I heard a clicking under the hood which was the parking light relay fluttering on and off. At this point we called it a day and turned it off, and while off the engine was making a clicking sound randomly that seemed to come from around the throttle body area. Couldn't pin that one down. 15-30 minutes later I smelled that electric burning smell we all fear. I felt the battery terminals and the positive terminal was to hot to touch for more than a quick second, way hotter than the negative terminal. At this point the vehicle would not even turn over. So, I unplugged the negative terminal and will return to figuring it out tomorrow. Any ideas what could cause this wide and strange array of electrical problems? Also, after replacing the relay, no further engine codes presented. Any help would be greatly appreciated. This one has me scratching my head.
