| On my Shorelandr boat trailer all my lights and my blinkers work fine. When its day time and my lights on my truck and trailer are off my left and right blinkers work fine also my brake lights as well. However come closer to evening when my lights activate my left blinker continues to work but for some reason my right blinker will not work. Just wonder if anyone has had this problem and put me on the right track before I start to troubleshoot. Thanks in advance for any advice and responses. |

| 1) Check your grounds. Most electrical issues on trailers, boats, etc. end up being something funky going on with a ground wire.
2) Make sure your connections to the tow vehicle is good. Mine does sort of a similar thing and all I have to do is unplug it and plug it back in and it works.
3) Are you certain the issue is isolated to your trailer? Test it out on a different vehicle in order to replicate the issue. Not far behind having a faulty ground giving you fits is thinking it's a trailer issue, when it ends up being an issue with the tow vehicle.
A basic circuit tester and a multimeter are your friends and are inexpensive. You might not think you "need" something like that but they sure are handy little time savers. |

Location: Cedarburg, WI | I'd second the grounding statement. Even if they "look" good and clean, I bet you'll find cleaning up the connection(s) where they tie to the frame will solve the issue. |

Location: Chicago | Was having some lighting issues last week... checking and cleaning the ground connections (and replacing the extension from my trailer to the truck) fixed everything. |

| The ground is always the first thing to check but it can be a variety of issues. I had something similar this spring. After checking and using a tester, I found out the problem was actually in the adapter I used to go from 7 pin to 4. Bought a new adapter, everything works. I had cleaned all pins/connections so it had to be something internal to the adapter. |
