so im driving along yesterday and check engine light comes on and speedo Dies...about an hour later everthing starts dying dash gets dim (this was a night btw) rpm needle dies, cd player shuts off and finally hids go bye bye. so alas i know my battery is dead. so i figure oh its my alternator Right? next morning i come back and just start figeting with fuses to see if anything blew and the Ecu Fuse was out??? pop in a new one get the battery charged and start it again just to see what happens ( no check engine light cuz i disconnected the batt to reset the ecu ) about 15 min later light comes back on and i check the fuse and its blown again?!?!?! well got a new alt changed it out didnt do **** and my buddy at autozone tested the battery and alt and noticed that the alt was barley putting out any charge nd the battery wasnt getting anything at all. (oh and my old alt was still good)

they figure its a bad ground somewhere or something but i have no idea where to start....

 

start by checking your grounds then and umm check ur main relay maybe?
