fusible link (alternator)

Hello ladies and gents. I don't know if you all remember but back in July I was having charging issues with my Crown Vic. I finally ended u changing he alternator. Well, yesterday while I was driving, the lil red battery light came on, I started losing power and shortly, I lost lights, gauges, everything. I JUST BOUGHT a new alternator in August! So I did some research and figured it could be a fusible link (or a battery). Reading up on the fusible link, it talks about cutting wires, splicing, crimping, soldering, etc...I guess I have two questions about this fusible link..First off, where is it? And secondly, would it be better (if even possible) to buy the wire with the link already in it? Cuz I don't know how to solder, even if I had that sort of equipment. Thank you for your time.

Re: fusible link (alternator)

Should be just off of the alternator, not always quite obivous. Last time I replaced one, I just bought a 6' roll (smallest quantity in the shop at the time) and crimped it on. Of course this was on a 1980 Datsun 200SX, don't know if there's anything that negates that way of doing things. Oh, and I ended up with about 5'8" laying in my tool box for years and years until I finally threw it away.

Re: fusible link (alternator)

The fusible link is located between the battery and the fuse/breaker box. Fusible links don't melt-down unless there is a short, and they are usually easily spotted by checking for a burnt spot and loss of continuity in the wiring harness.

You should find and fix the short before replacing the link. If the short is in the main wiring harness, then you should consider replacing the entire harness as it's overall condition would be questionable. That will also take care of the fusible link replacement.

Beware, wiring harnesses are expensive. Make sure that's the problem before throwing money at the problem.
