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.
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.
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.
