Fusable links have the amperage amount wrote on the wire itself. You would need a fuse holder with the same amperage fuse as the wire states.

No it didn't plus the fact it was badly corroded there was nothing left to read except farther down the wire where it said 10 gauge. I replaced it with a 140 amp fuse and some 8 gauge audio wire I had.

10 gauge is hard to find Belkin doesn't make it and a local auto electric shop said they couldn't get it either. The dealer wanted $300 for the positive battery terminal with about 1 foot of that fuse link wire attached!!!!!!!

Schematics are showing 12 gauge. It isn't stating the protection amount. If your talking the big black one that feeds the power distibution center the best advice would be a local scrap yard. Probably less the $5.
Or 2.95 ordered from here http://www.madelectrical.com/catalog/fusible-link.shtml
I would go with the scrap yard personally. It'll be the correct length and protection amount.

For 12 gauge I'm finding 160 amp fuse protection. If the wire is stating it's 10 gauge,you want a fusible link that is 4 times smaller then the wire it's protecting. So you would want a 14 gauge fusible link.

Heres a link explaining fusible links and the alternative to replacing them. http://knizefamily.net/minimopar/electrical-links.html

No it was the one coming off the positive battery terminal that goes straight to the alternator. 10 gauge. The alternator is 130 amp so I replaced it with a 140 amp fuse and it's been fine since.
