Renault Magnum is a mainline tractor unit produced in four generations from 1990 to 2014 with different engine capacities. The most popular were the Renault Magnum dxi engines with a capacity of 440, 460 and 480 hp. In this publication, we will show a description of the fuses and relays of the Renault Magnum with block diagrams and their locations. Note the fuse responsible for the cigarette lighter.
The design of the blocks and the purpose of the elements in them depend 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.
Fuse and relay box
The main fuse and relay box is located at the top of the instrument panel, on the passenger side behind a protective cover.
