85 Fleetwood Brougham won't crank, blowing fusible link

[jp233]

Ok, Layla hasnt run in almost a year. last year i had problems getting her to crank so i replaced all the old fusible links with new links with removable fuses, and put a new starter in it too. well now that i want to sell of course she wont start. the battery was hurting so i put a new battery in, but now it continually blows a 30A on a fusible link that leads from the + battery terminal to a black wire that goes back to God-knows-where. my haynes manual has crappy generic wiring diagrams. anyone have any idea where this black wire goes, or any other suggestions? I want to sell it in a running condition.

BTW - 1985 Caddy Fleetwood Brougham, limo
