Trailer brake issues.

[Sesco4]

Had to pull my 16ft utility trailer yesterday and the alarm or chime whatever you wanna call it kept going off while driving. The trailer on the factory trailer brake would flash red and where the odometer is would show check trailer. I pulled over and checked everything and it looked good. I use the trailer on a regular basis and its done it before but yesterday the alarm kept going off every few minutes. Any ideas where to start troubleshooting.

Thanks

Mine gets mad at me every now and then. Is the ground looking ok? I found that my trailer wires were crap and green. Now this is on the 18' hauler.

On my boat..... it doesnt even work unless it gets re wired every year. CRAP!

I had the same issue, after some major research i found it out to be the ground. for a quick fix i took a flat 4 pin trailer harness and grounded out the connector to the frame of trailer and the other on the truck, but i did them backward as commpaird to a normal trailer hook up. ( put the male connector on the truck side ) so no one would hook it up to the lights by mistake and pop fuse. since then ive never had the "check trailer annoying bell again" im going to find the ground in both trailer side and truck and just rewire them so it will look more professial.

Did you fix this yet?

When we get those problems at work, check the wiring and plugs first. Then check your brakes.

Yes sir Galaxie, I have. find you trailer ground and make sure its a sure enough no joke ground. ive found that some trailer manufatures dont use a heavy enough gauge wire for the ground. i know it sounds crazy but it is for real. some trailers will use a small wire but its grounded close to the hitch so there isnt much wire needed. others may be far down the trailer somewhere. I know it doesnt sound right but its kinda the same princible of useing a test lead that is very small and trying to make it carry a current to test somthing like a light, and it just cant power it. Same on the truck just make sure the pins on the connectors are clean i spray WD40 in it and works fine. and check the truck ground to. havent had anymore issues except when one of my crews drug the plug the road and wore off the lock tab. Hopes this helps you guys! C.B

my trailer light was doing the same thing now everytime i start truck its say ebc fault !!! electronic brake controller is going out ! for the longest time i thought it was the boat but hooked up to a buddies truck and they worked like they were suppose too. so could this still be a ground issue ???
the controller actually works a little i have to set it on ten (which is way off from before) and if i have to make a panic stop i can manually activate them!!! STROKEDIS
