Fuse box diagram (fuse layout), location and assignment of fuses and relays Ram Trucks 1500, 2500, 3500 (2013, 2014, 2015, 2016, 2017, 2018).
Note
- Before replacing a fuse check that the key has been removed from the ignition and that all the services are switched off and/or disengaged.
- When replacing a blown fuse, it is important to use only a fuse having the correct amperage rating. The use of a fuse with a rating other than indicated may result in a dangerous electrical system overload.
- If a properly rated fuse continues to blow, it indicates a problem in the circuit that must be corrected.
Engine Compartment Fuse Box Diagram
The Power Distribution Center is located in the engine compartment near the battery. This center contains cartridge fuses, micro fuses, relays, and circuit breakers. A description of each fuse and component may be stamped on the inside cover, otherwise, the cavity number of each fuse is stamped on the inside cover that corresponds to the following chart.
