Foton Auman is a family of truck, dump trucks and flatbed trucks produced from 2003 to the present day in various modifications and versions. In this article we will present a description of fuses and relays Foton Auman with schematics of blocks, their locations and photo examples of performance. Let’s highlight the cigarette lighter fuse.
Fuse and relay assignment may differ from the one shown and depends on the year of manufacture and the level of electrical equipment.
Fuse box in the passenger compartment
In the passenger compartment, the main fuse and relay box is mounted under the instrument panel on the passenger side and is covered with a protective cover. It consists of a main section and additional sections (LR LL and RL RR).
