Renault Magnum – fuse and relay

Renault Magnum is a long-haul truck produced in four generations from 1990 to 2014 with different engine sizes. The most popular are the Renault Magnum dxi engines with a capacity of 440, 460 and 480 hp. from. In this publication, we show a designation of Renault Magnum fuses and relays with boxes diagrams and their locations. Note the fuse responsible for the cigarette lighter.
