I have a 66 Dodge Coronet 440. All of a sudden the drivers side brake, turn signal and tail light went out. The bulb looks good. Fuses all look good. And the drivers side headlight will not work. But when the brights are on it works and the back taillight will work also. Anyone have any ideas on what it could be or how to troubleshoot it?

 

What is your experience level with electrical? I dont want to talk down to you, or spend time telling you stuff you already know. Do you have a digital multi meter, or any kind of tester that you know how to use?

 

Are your grounds all connected? I had issues with mine and they only worked with the flashers on, turned out the ground was off.
