    Hi Everyone,

    So I have a 2003 Chevy Trailblazer and just had a low-beam go out. Bought replacement bulbs and went to go put them in last night and found this...

    This is the power cable that connects directly to the bulb inside my headlight enclosure.


    My inclination is that it was just a bad connector that finally burned up. I see no other signs of damage anywhere, in either headlight, or in the other connectors on the outside of the enclosure.

    I've ordered a new lead and will be splicing it in when it arrives.

    Are there any places in particular I need to take a look to make sure I'm not going to burn this one up either? These little damn leads are expensive, and I don't want to risk a bigger another fire somewhere else down the line.

    Thanks

    Probably had a bad crimp on the connector terminal to the wire; if a bunch of the strands of the wire are broken off and not in the crimp, the crimp area will get VERY hot, resulting in what you have. High-current crimps require a lot of care to ensure you get the whole wire in the crimp.

    Make sure the circuit has the correct fuse. Otherwise you will probably be okay. As was mentioned before you probably had a high resistance there that turned the connector into a heating element. Replace it with a new one and make sure the splices are good (I prefer solder and heat-shrink tubing) and it'll be fine.
