So i bought this 1984 2wd le van 3 months ago. i love it, but there has been a series of problems ending in total electrical loss. to start i was driving on the highway and had to slam the brakes and the battery slid foreward in the box to the point where the positive lead was touching the box and over the next 5-10 minutes of driving i lost all power to accesories and when i turned on the lights it died. i tried to charge the batter by running the car once i jumped it but that killed the alternator. so when i pulled the alternator, i changed the belts aswell because they were on the way out. i get it all back together and take off and while im at the atm i lose all power but the engine was running so i drove home. and here i am. no power at all anywhere in the van, 12.75 volts on the battery. where should i start?
