MCRideFan53 Posted April 18 Report Share Posted April 18 Hey everyone, Someone jumped my truck and hooked the wires up backwards for a moment, immediately blew the red and black fusible links. What gauge are these? I've never dealt with these before, the guys at the parts store didn't seem to know anything. Can't seem to figure out what amperage they're rated for. Thanks!

Found this when I had an issue with my Fusable link, I just bypassed it but not sure it it will cause damage to something. Starts just fine though. Quote Link to comment
datzenmike Posted April 18 Report Share Posted April 18 This is what Nissan uses... You can probably buy the same rating from another maker that may be different color. You absolutely must not use a higher rating. Fusible links can survive short term currents far above their rating. Use similar wire lengths and solder them in. 1 Quote Link to comment

Starts just fine though. The fusible links are only there in case of catastrophic damage not experienced in normal operation. The power wires from the battery to the ignition, lights and to the fuse box have to be fused. An accident can pinch these wires causing a short where hundreds of battery amps flowing through wireds to ground will light them up like a toaster and cause a fire. Fusible links are insulated with Hypalon plastic that resists ignition while the wires inside melt and break the circuit. Ordinary wires of the proper size will do the same but the plastic will catch fire. Quote Link to comment
Joecar Posted April 18 Report Share Posted April 18 Might have to address this then. I had a guy fix it for me cause the truck would not crank at all so the only way I could was to remove it and do something. Quote Link to comment
Stoffregen Motorsports Posted April 18 Report Share Posted April 18 Fusible link wires should be 4 sizes (numerically) smaller than the wire they are protecting, and should be cut to the same length as the original fusible link. If the wire ga is 10, then the fuse link would be 14ga. It gets tricky figuring out the gauge on Japanese cars, but there are markings on the wires and if you can still read them after all these years, you can convert the metric size to AWG. In a pinch, you can always strip the wire and measure it with a digital caliper. https://www.lapptannehill.com/resources/technical-information/metric-to-awg-conversion-chart PICO sells fusible link by the foot. 1 Quote Link to comment
Thomas Perkins Posted April 18 Report Share Posted April 18 (edited) Their are Nissan sites on facebook that have used fusible links for sale.Do you want me find you one?Does this look like your's?You may have to use your metal piece if it won't have one.

Joecar Posted April 18 Report Share Posted April 18 I forgot what it looked like. I will send a picture of what my cables look like once I get my truck 1 Quote Link to comment
Thomas Perkins Posted April 18 Report Share Posted April 18 (edited) Orielly's has the fusible link wire with the O rings connected to them.Take your's with you and match them up.Get connectors for the other side. I have a brand new fusible link,but I am keeping it. Edited April 18 by Thomas Perkins Quote Link to comment
Joecar Posted April 18 Report Share Posted April 18 I don’t have the original fusible link anymore, guy I took it too must have throw it away or something but it was all chopped up too from previous repairs. Quote Link to comment
Thomas Perkins Posted April 18 Report Share Posted April 18 (edited) Do you have the white ends that they connect to?No big deal if you don't.I used these yellow connectors on mine, long ago,mine dry rotted.Want me find you one? Edited April 18 by Thomas Perkins Quote Link to comment
Stoffregen Motorsports Posted April 18 Report Share Posted April 18 Those connector housings are pretty generic. I bet you could find some on that Japanese motorcycle wiring supply website. Here - https://www.vintageconnections.com/collections/connectors 1 Quote Link to comment

Thomas Perkins Posted April 19 Report Share Posted April 19 I just got a response from a friend that has used fusible links.Do you want one or anybody else. Quote Link to comment
Thomas Perkins Posted April 19 Report Share Posted April 19 I just sent him a request on price and pictures.They are very hard to find. Quote Link to comment
