Fusebox

Fuses

Fuses protect your car from electrical short circuits and power overloads that can damage equipment or start a fire. Often, a fuse will blow due to a momentary overload, and replacing the bad fuse as directed below will fix the problem (the car's horn or interior lights may cease to work, for example). If a fuse blows repeatedly, it indicates an electrical problem that will require a little trip to your Lotus Dealer. The wires can corrode on the reverse of the fusebox and break off. If this happens new clip in fuse terminals can be sourced from Smart car dealers, part number 011 545 84 26 or 004 545 52 26, both parts numbers are correct. Simply solder them onto the wire and push fit them into a spare socket in the fusebox, then mark up your handbook with the change.

Never replace a fuse with one of bigger amperage. This could damage the device the fuse is meant to protect.

Toyota Elise S2 Interior Fuses & Relays

The wash/wipe module, turn/hazard flasher relay, horn relay and a relay for inertia switch activation of the central door locking, are mounted on the scuttle beam above the passenger footwell, with four fuses secured to the harness in that area.

A 60A Maxi fuse protecting the ABS circuit is located beneath the passenger side fascia top, adjacent to the positive post. A multi-function relay unit containing the engine control relay, fuel pump relay and starter relay is mounted in the engine bay near the ECU. A similar relay unit is mounted in the front services compartment alongside the fusebox, and operates the a.c. compressor and radiator fans.

Interior fuses

Important Note: Although the two modules are identical in appearance, their function is different and they must not be transposed.

The A.C. relay module A117M0038F has a brown label marked YWB100800.

The engine relay module A111E6024F has a white label marked YWB100970.
