So today i was picking up my new car, and the battery died in my 89. Well, i took the battery from my new car and put it in my old car, so i could get it out of the way. Well, i hooked up the terminals wrong, aka opposite. The fuse box under the hood smoked, and now it seems like theres no power coming from the alternator, like its just all coming from the battery. I got it halfway home before it died. Now what have I got myself into?
