  Q: How is the Fuse Box designed to safeguard electrical circuits and How to replace fuses on Mazda MX-5 Miata?

  A:

  A mix of fuses, circuit breakers and fusible links ensure the safety of electrical circuits of the vehicle, the main fuse and relay block is in the engine compartment on the passenger side of the dashboard, and the interior fuse box is below the instrument panel on the driver side of the dashboard. Each fuse is assigned to a certain circuit that can be determined in the fuse panel. Main fuse block feeds high current circuits like fuel injection, Headlights and cooling fans whereas the interior fuse box feeds circuits to interior lights, radio, door locks, power windows, instrument panel, wipers, and exterior lights. The main fuse block and the fuse box contain miniaturized fuses, except the 80-amp main fuse. The fuse puller tool should be utilized when changing fuse otherwise it will be damaged. Should an electrical part become faulty, it is best to check the fuses first and a test light may be used to check whether a fuse is blown. In order to change the main fuse with 80 amps, the negative battery cable should be disconnected, and the fuse box cover should be opened to change the fuse and make sure that the two fuse wires are in place. The replacement of blown fuses with the right type is essential because the application of the fuse of different ratings may provide the wrong protection of the circuits. When a replacement fuse fails instantly, this is a sign of a more serious problem, usually a short in the wiring or a failed component, and should not be replaced again until the problem is fixed. To replace the burnt fuse, the light on the dashboard malfunction will be set on, and to replace it, it needs to first be switched to Lock before a new fuse is installed.
