Fusible Link

The one from the battery cable to the junction block behind the battery....is it really just a 14awg wire or is there something special about it? The local parts store only had the type with an actual fuse installed. Can I use a section of 14 awg wire and does the length matter?

Thanks

Re: Fusible Link

It is supposed to be "fusible link" wire. NAPA sells it 10' rolls. Not terribly expensive.

Re: Fusible Link

I have another store to check that is closer than NAPA (wish those were common here) but will head there if need be. Thanks

Re: Fusible Link

Sorry. Need to update my profile. Im in South Florida now but AutoZone was the next store I was going to check. Seems to be harder to find stores that have a lot of these parts in stock for our old cars. Bennett Auto Supply didnt even have a tranny filter and gasket for 700r4 transmission!

Im whinning now. I'll stop

Re: Fusible Link

The wire is not copper strand automotive wire. It is made of nickel-chrome steel wire (same stuff as glows red in your toaster) and is rated to carry Amperage in different amounts. Here is a picture of the wire without the poly-chloride vinyl plastic insulation:



If you are thinking of upgrading your wiring I recommend buying a circuit breaker rather than a fuse as a circuit breaker will rest and not leave you stranded on the side of the road.



These circuit breakers are also sold by amperage rating. The amperage rated is related to the rated capacity of your car's ORIGINAL alternator. If it was replaced with a 120 Amp one wire alternator to feed your power hungry stereo amplifier then your car could burn to the ground as the factory wiring isn't sized (gage of wire) to conduct that much power.

So a 36 Amp rated alternator would have a 40 Amp fusible link. A 67 Amp alternator would have a 70 Amp rated fusible link. You can buy circuit breakers sized in 5 Amp increments.

Re: Fusible Link

DOH!! I just ran to Auto Zone and bought 9" of 14awg universal fusible link. My wiring is not really upgraded per se. I just replaced everything forward of the firewall with AAW factory fit harnesses. I do have a 105amp alternator in there....

Thanks for the suggestion though.
