No Power to ignition on 94 loyale

[daneman]

Help please. Going nuts. I have power at the fusable link (white) but no power at the fuse box. Sometimes it will power and start. If I run a jumper wire from another point on the fuse box to the ignition or white wire input side of the fuse panel everything works. Is there a relay or something between the fusible link and the fuse box? Would it hurt to run new wire from fusble link to input side of fuse panel? Am I looking at this correctly? I have found no wiring diagrams, and following wires is difficult on these cars. Any toughts, ideas or solutions would be highly appreciated.

Thanks.
