Trailer circuit problem

Hi all,

I sold the 83 and got myself a newer truck. A 2000 F250 CC SB 7.3. It's a great truck and I've had only minor issues. Recently I found out the the trailer right turn signal doesn't work. I found the fuse missing under the hood but after installing a fuse there is no power, even at the fuse hot side. I tried looking for a relay but I couldn't find a specific relay that controls the circuit but no luck. Everything works fine I the truck. It's only the right turn trailer circuit.

Does anyone have any ideas on where I should look next?

run a temporary wire from battery to fuse in fuse box... does the trailer light work.


if it does.. broken wire/bad connection between main power into fuse box and the connector for THAT fuse.

Test both the truck connector and the trailer connector, for a complete circuit.

Wires in connectors frequently loosen and cause problems.

Tighten any loose screws.
