Trailer left blinker suddenly not working

[Ivans]

Anyone knows how can i check ground connection on a trailer? There is no cable attached to any nut around the trailer. Ive got a savage trailer with y connector wiring harness. Its got a round end connector. Thanks in advance.

Take apart round connector and make sure everything is connected.
mostly only one or two screws to take apart.

yeah also the pins in the connector can get a bit loose, if that's the case put a flat blade screw driver in the gap and open it up a little bit for better contact.

Yup took it apart and checked the cable connections, they are tight and connected.
I ll try open up the pin as the other said

My trailer is earthed through the plug to the car. No earth on the trailer. Are they led or globes. Is power getting to the blinker. A bad earth would affect all lights the lens is not cracked allowing water in. This happened to one of my trailer lights.

If that's not problem , check if globe is stuffed.
Or wire has come loose on actuall talight

They re led. Car earth should be good I have no problems with car lights. All lens are checked out. Maybe it just died but hard to believe as it’s rarely used

I prefer led lights with the wiring that terminates at the plug ie no joins at the back of the light. If yours connects at the light check the connection it might be corroded
