Blown Fuse

[Cal777]

On our ride the weekend I noticed that we didn't have lights on our 622 trailer. When we got home I checked the fuses and F7 was blown. I disconnected the trailer and replaced the fuse and it blew right away. Would that suggest a bad trailer module? Any help would be appreciated.
Thanks in advance. Rudy

Bad trailer module or improperly installed module and the wires contacted the tire or belt. Disconnect the trailer and replace the fuse, so you will have reverse gear (if it was a module problem), and then see your dealer. It probably won't still be under warranty unless it was installed by the dealer at the time of delivery, and specifically listed on the warranty registration.
