Having a new battery and cables doesn't necessarily mean your side posts aren't loose. But if you're blowing fusible links, you have a larger problem. You need to find the short. You need a wiring diagram, and then follow the wiring southward from the fusible links to see where it's rubbing or what component is melted.

Thats what i figured.i havent blown any since i just replaced them all since i was in there. Next question which shows my true ignorance of electrical. So i understand what a fusible link does and how. So if i put a higher rated link in it wont effect anything downline or keep it feom working right? Only if it were to blow agaiin it would allow that much more electricity by until burning it self out. Correct?? Thanks again for everyones help

DO NOT replace a fusible link with a higher rated link. You don't want a short that may be close to causing a fire to be able to have more heat.

I’d revisit the shop manual - pretty sure that the 1990 is available as a download here. Alternately, check alldatadiy.com as their subscriptions are pulled from the GM manuals.

For example, attached is part of a 1992 manual that troubleshoots pump priming.
