So i posted a threat a while ago about this problem but now im finding more info out about it. My instrument gauge fuse will blow and when that happens the battery wont get charged by the alt. I know theres a short somewhere but i have no idea where to start. its a 1995 ls. any help would be amazing

 

Wiring problems are, IMHO, the worst problems to track down. I would recommend you purchase a factory service manual set, get comfy, and start reading through the wiring diagrams until you know which circuits are on that fuse and what connectors are involved. Then start probing out the wires with a multimeter, looking for shorts to ground in the main power wires.
