Toyota 90982-08306 Fusible Link

Protection of electrical circuits of the vehicle is provided by fuses, circuit breakers, and fusible links; main fuse/relay panel is mounted in the engine compartment and interior fuse box is on the driver's side of the instrument panel. Several types of fuses are used, small, medium and large and all use the same blade terminal layout, the small fuses require the use of pliers or a plastic fuse extractor to remove. Electrical component often corrodes leading to a failure and in any case of failure, one should first check the fuse which can be done by using a test light where a blown fuse can be decided by checking for power at the terminal tips, moreover, one should be able to identify a fuse that has been blown from the melted element. When replacing fused items, it is important that you use the right fuse because aside from the physical appearance, the standard fuse has a different amperage compared to the electronic fuse. In the case that first changed fuse burns out instantly, there could be a short circuit, which one should thoroughly look into before changing fuses. Select circuits are protected by fusible links, more prevalent in the high-current applications, which can be resoldered after removing the negative cable to ground. Individual circuits such as that for the power windows and heated seats have circuit breakers that automatically reset when they trip; if one does not reset, one needs to check it immediately. For the basic check, it is recommended to use a voltmeter to test if the circuit breaker has battery voltage available at each end of the circuit and some may need to be manually reset.

Each fuse is designed to protect a specific circuit.

The fuse panel itself identifies the various circuits.

Miniaturized fuses with a blade terminal design are employed in the fuse blocks, allowing for fingertip removal and replacement.

Some circuits are protected by fusible links, which are used in circuits that are not ordinarily fused, such as the ignition circuit, or circuits that carry high current.

If you have to replace a blown fusible link, make sure to replace it with one of the same specification. If the replacement fusible link blows in the same circuit, troubleshoot the circuit in which the fusible link melted before installing another fusible link.

Several sizes of fuses are employed in the fuse blocks, including small, medium, and large sizes, all with the same blade terminal design. Medium and large fuses can be removed with fingers, while small fuses require pliers or a small plastic fuse-puller tool found in most fuse boxes.
