Trailer wiring not working

[spphil]

The left turn signal and brake light to the trailer are not working. The trailer lamp is working . I tested it with my Fluke mutimeter and there is no voltage at the pin connector on either the 4 pin or the 8 pin. Does anyone know if there is fuse in the circuit??

Yes there will be a fuse. I work for U-Haul so I deal with this all the time. Your trailer lights are fused separate from the truck lights. Trailer taillights, Left turn/brake and Right turn/brake are each on their own respective circuit.

There is most likely a fuse for each of the 6 wires going to the 7 pin plug (the 4 pin is just paralleled). Look I the fuse box for circuits labeled Trailer Tow

OK I looked in the owners manual (I know I should have looked there first. I'm 72 that's my excuse ) It is fuse F09 for the left and F10 for the right . F09 was blown . I replaced the fuse and hookup the trailer and it is working. Thank you for the replies
