Another trailer lite question

[sea wolf]

Well, here goes. I'll explain as best I can. With the forward side marker lite plugged in, only 1 tail lite will work, on the right side & nothing else such as the 3 bar. If I unplug the marker lite, all the lites will work., except for the left side tail lite which needs to be replaced. I also have no brake lites or signals. Anyone have any ideas? I have a 4 pin connector.

Usually a ground problem or sometimes the element of a burned out two element bulb sags and touches the remain element. Sends current in directions never intended.

Well, in desperation I got out my Dremel & cut the lens on the taillight {sealed}. I changed the bulb & that lite now works. I will head to wally world tomorrow for a replacement. But no brake or signal lites. There are 2 connectors on the marker lite,so I plugged the wire into the other connector, so now all the lites work except the brake & signals. I tried the 4- ways also, nothing. I'm taking a trip Thurs., & don't have time to rewire these damn lites!

Re: Another trailer lite question

Did they all work before? Did you change something to cause the problem?<br /><br />Dumb question, I know.. But had to ask.<br /><br />Trailer wiring is quite simple. Just step back and take one circuit at a time. Don't try and make it worse by thinking about the whole thing at once.<br /><br />If you got fire on your plug at the tow vehicle, then trace from there. One wire at a time.<br /><br /><br />I had a similar situation as yours. It turned out to be a factory ****-poor job when they wired the trailer. They had poor un-soldered connections up inside the frame.<br /><br />I would also suggest getting a set of the LED lights. You might as well since you have to buy a new light anyway. I got mine off EBay real cheap.<br /><br /><br />H.

First thing everyone should own is a 12 volt test light, if you don’t have one you will be lost from the start. Any auto parts store should have one $4 to $10 range. My 2 cents.
