Hot (headlamp) wiring!

I have just found that one of my headlamp wires has signs of heat affecting it, so much so that the plastic connector block has partly melted. The wiring insulation adjacent to the block is slighlty blackened.

I found this when replacing the bulb, due to the dipped beam not worling on one side. Having got it all apart I pulled the bulb from the 3 blade connector and left behind one of the male bulb terminal blades in the connector. Reckon the heat had melted the solder holding it to the bulb fitting..

This is worrying; the bulb is standard so I don't know why this has happened.

Advice as to getting a replacement connector would be appreciated plus any ideas to stop further heat in this wire. (I have checked the fuse and its the right rating..)
 
A trick some people have tried to get better performing headlights is to intstall a different voltage regulator on the alternator bumping up the voltage. Might be worth double checking that this hasn't been done to your car as the inevitable side effect is higher current and the risk of overloading some of the standard wires/electrics. Failing that it could just be that part of the loom is starting to suffer the effects of age.

When the engine is ticking over with no electrics on, if you put a volt meter/multi meter across the battery terminals you should be getting around 14v. If you are getting significanly more then it might be a higher rated voltage regulator has been fitted.
