Steph and Dud B Posted October 14, 2023 Share Posted October 14, 2023 Did they work for you before and just stop working? How old is your Oliver?

Keith Kaiser Posted October 14, 2023 Author Share Posted October 14, 2023 Oliver is 2022 LE II. We know they worked last spring when we towed from TX to WA. Been sitting in WA all summer, during which time we haven't towed it. 1 Link to comment Share on other sites More sharing options...
Steph and Dud B Posted October 14, 2023 Share Posted October 14, 2023 The most common cause of failure is the 7 pin plug and connector between the truck and trailer. Check the contacts on each for bent connectors or corrosion. (I've been able to resurrect a trailer connector in the past by gently bending a prong back into place with a flathead screwdriver, but with a trailer so new yours shouldn't be that worn.) CAUTION: Pin 4 on both truck and trailer may be "hot" (connected to the battery) at all times in some installations, so don't short that one out. 2 3 Stephanie and Dudley from CT. 2022 LE2, Hull #1150: Eggcelsior.

Moderators topgun2 Posted October 14, 2023 Moderators Share Posted October 14, 2023 A "Q-tip" to help clean things out and then some dielectric grease - you can put that in the trailer plug with another "Q-tip". Past that - check your fuses.
