I have no running lights on my 2006 Peterbilt 387 all of the lights work
Dead short in the trailer wiring or one of the trailer light sockets.
The trailer has a dead short in that right side brake light circuit.
There isn't a specific fuse for it... power is supplied to that circuit by existing fuses. You probably have a bad switch.
On a 2006 Lincoln Navigator : # 106 is a 30 amp maxi fuse for the ( trailer tow battery charge relay , trailer tow 7 - wire connector , battery charge )
short circuit on trailer light wiring
check the fuse in the underhood fuse box. There are separate fuses for the trailer turn circuits and tail lights. If the fuse is burnt, replace and reconnect the trailer. If the fuse blows again, check the trailer wiring for a short on the park light wire.
On my 1999 Explorer it is fuse #30 labelled "Park Lamp/Trailer Tow Relay" in the passenger compartment fuse panel Page 183 of Owners Guide

Fuses are designed and intended to protect the wiring from SHORT CIRCUITS and OVERLOADING. When a fuse "blows" instantly upon connecting the trailer wiring to the vehicle wiring connector,suggests a short in the trailer wiring, or one of the light sockets/fixtures. If the fuse did not blow instantly, but over a period of minutes, would be suggestive ofan overload condition. Sinceit blows the tail light fuse, logic suggests the short should be found in the tail light wires or bulb sockets on the trailer. Another possibility, but very remote, is a defect in one or both of the connector plugs. Look for an area ofcut or chaffed insulation onthe trailer tail light wires, where the wire may be "pinched" in a crevicebetween twometal members of the trailer frame, OR where the wire makes a very sharp turn around a metal edge.j3h. you have a short in the tail light wiring of the trailer
Yes, all circuits are protected by a fuse.
