New trailer wiring for my 06 Nissan Maxima wont work on traile
Just had new wiring installed for a trailer. When hooked up to two brand new trailers, signals will turn on once then shut off, left, right, and hazard do the same thing. The "trailer doc" says the wiring is fine (electronic gadget by installers). The signals won't start again unless the car is restarted. Everything works fine when it is not hooked to the trailer. Any suggestions?

Have you tried a heavy duty flasher? Also, if your signals & brake lights are 2 different bulbs, as in amber for signals & red for stop, then you will need a small in line converter to separate those 2 as most vehicles use same bulb for signal & stop.

If the blinker is working on the truck then fuse is good, this sounds like a bad bulb or connection to the light, the brake and signal use the same filement in the bulb. check the bulb first, next thing to determine if its the trailer wiring or the truck socket, use a testlight and test the connector or the wire at the trailer connector and see if there power in the wire, but check close to connector if theres power coming out the connector then it in the trailer wiring or bulb,. also im not sure what this trailer turn relay rh is that you speak off. the only thing i could think of is to converter the signal and brake on the truck to operate the same bulb on the trailer, if this is what you installed then check that wiring also as the controls the lights to the trailer, but if this truck was built with the tow package then it should of be wiring already for this. here a good site to help you with the wiring as this gets hard to explain over the computer, but again test the tow connector on the truck first with a testlight, this way you will be able to see if it the trailer wiring or the truck wiring to connector. google trailerlightwiring. good day. let me know if you have any other questions.
If the Nison lights are working it has to be the wireing from the car to the trailer or the left bulb or socket on the trailer. Also if this trailer wasen't wired for this spicific car it probably won't work right anyway. When checking the wireing I find that findind the ground wire on both the car and trailer are one and the same at the connection . Then it just a matter of checking each wire with a batery to determine which wire is for which light. And making the right connection to the car. Some cars the signal wire and the brake light wire are the same wire .
The truck is protecting itself from the load impose by the trailer.. Chk the plug on the truck for wire gauge size. Turn any electrical loads off on the trailer, any and all. If fuse still blows then the fuse is either underated or the trailer has a dead short. In fact turn trail main power panel of. All lights work you say. So ck the inverter for defect byturning off the inverter on one of the trailers.
Are you checking your lighting with the trailer hooked up? This is the trailer's ground source. The white wire on both sides of the plug is the ground wire. Grounds are very important, Make sure they good and clean.
