Factory Fusible Link, Brown (formerly Red), 76-78 280Z

Includes:

• (1) 0.3 mm² Brown Fusible Link

Description:
This is a genuine, original equipment (OEM) Nissan 0.3 mm² Brown Fusible Link. Fusible links are a critical safety component for early Z-Cars. Their function is similar to other fuse types since they protect the electrical system - from damage in one component - spreading to the whole circuit. When too much power flows through the circuit due to a problem (short circuit, etc.) the Fusible Link which is in that circuit will be the first item to fail (or burn out/melt), which then cuts the power to the circuit, and whatever part/wire/connection/etc. is causing the problem. While it is possible for Fusible Links to burn out simply from old age, they are the safety valve, not the problem to be fixed. Whenver a Fusible Link fails, that electrical circuit must be tested for whatever problem caused the fuse (Fusible Link) to fail. This is especially true if more than one link has burned out at the same time or if you have replaced the same link previously. If you just replace the Fusible Link and ignore the circuit, the link may fail again, or whatever caused the link to burn could cause a catastrophic failure, sometimes even resulting in a fire. Fusible links are sold individually; see below for the quantity your car needs. Need to replace more than one link, all of your links, or the covers?

Fusible Link Safety:
Fusible Links are much more than a length of wire. They are specifically designed using a special type of wire construction, with special safety insulation made of heat-resistant cross linked CPE (Chlorinated Polyethylene). Using regular wire in place of a fusible link, even in an emergency situation, is extremely dangerous. This is true even if you choose standard wire that is smaller than the circuit, because of the level of fire-resistant insulation. If you use a standard wire that is the same size or larger than the circuit, you are at a high risk of catastrophic failure of what is in that circuit, or even a car fire. We recommend always having spare Fuses and Fusible Links stored in your Z, especially if you travel.

77-78 Link Position:
Unfortunately Nissan's documentation about the position for the Fusible Links is inaccurate for the 77-78 model years. While the proper original position of the Black 1.25mm² would be on the outboard fender side of the front box, Nissan's consistency over the years has been gray at times, and with some Z's having been re-wired or re-harnessed, or even where the harness or Fusible Link housings may have been reinstalled incorrectly, a check of the wiring going to the Fusible Link housings is a simple way to confirm the proper location. Assuming original wiring, each Fusible Link housing has 2 White/Red wires and 2 White wires attached underneath. One of the White/Red wires is larger, approximately 4.5mm thick, than the other three, which are approximately 4mm thick. The larger White/Red wire is the proper location for the Black 1.25mm² Fusible Link. If you think your wiring has been replaced at some point, or cannot measure this difference in thickness, we would suggest tracing the circuits based on the wiring diagram in the Factory Service Manual, or having a knowledgeable technician do so.
