Fuse box diagram Isuzu N-Series (Elf) and relay with assignment and location (2022)

Isuzu Elf is a series of commercial trucks manufactured by the Isuzu concern, which has been produced from 1954 to the present in six generations with various modifications and types of engines. Known outside of Japan as the N-series (NQR 75, NPR 71 and many others). In this article, we will present a description of the Isuzu Elf N-Series fuses and relays with fuse box diagrams, their locations and photo examples of performance for the 5th generation (1989, 1990, 1991, 1992, 1993, 1994, 1995, 1996, 1997, 1998, 1999, 2000 , 2001, 2002, 2003, 2004, 2005, 2006) and 6 generations (2007, 2008, 2009, 2010, 2011, 2012, 2013, 2014, 2015, 2016, 2017, 2018, 2019, 2020). Select the cigarette lighter fuse.
