Hi all,

started having intermittent trouble with my headlights yesterday and looked into it today.
Found the issue was with was the spade connector to the fuse box which had either corroded - or melted. (see picture).

Would people say that this was corroded or melted (I can't tell).
i.e. failure caused by age and time - or by heat ?

Last summer I put a pair of spots on the car (carefully wired into the high beam circuit, separate relay, inline fuse and
tick all the boxes for careful wiring etc - but not switched - high beam comes on and the spots come on too).
Never had any problems with them until yesterday when the whole lighting system started to have a personality.

My quick fix today was just to replace the connection to the fuse box with a new spade connector and all seems
well but I'm wondering if I've missed something fundamental when wiring in the spots which might heat up the
connection to the left side of fuse box.

There's no real rust or grot to see and the rest of the fuse box and all connectors seem pretty clean which makes me think
that one cable may be heating.

All and any advice / opinions / experience very welcome.

Best wishes
Monty

Looks melted to me.....

I second melted, would also say do you run spot lamps? with no relay? and Id make sure the connections shine on the terminals as for it to get warm there it would indicate corrosion of sorts

Will probably be a combination of both. Corrosion leads to a poor electrical contact, which in turn generates heat as a result of the resistance caused by the corrosion and melts the fuse box.
Clean the spade terminals as best you can. Close them up slightly with a pair of pliers to ensure a tight fit and replace the fuse box.
