Renault Magnum is a long-haul truck tractor that was produced in four generations from 1990 to 2014 with different engine capacities. The most popular were the Renault Magnum DXI engines with 440, 460 and 480 hp. In this publication, we will show a description of the Renault Magnum fuses and relays with block diagrams and their locations. We will note the fuse responsible for the cigarette lighter.

The design of the blocks and the purpose of the elements in them depends on the year of manufacture, generation and engine. Check the purpose with your description on the back of the protective cover or other technical documentation.

Renault Magnum fuse and relay block

The main fuse and relay block is located at the top of the instrument panel on the passenger side behind a protective cover.
