Re: Headlights problem on XJ 1992
The clue that I twigged on was "connection on headlamp switch (tan colour
wire) was a little bit melted". Something made that connection hot,
either over-load or corrosion. He says that he's replaced both the light
switch and the headlamp dimmer switch, it would be good to know if this
problem was the reason he changed out the switches or if there was
something else going on. Either way it sounds like he's tripping the
breaker, it doesn't seem likely that a bad ground is going to cause that.

Re: Headlights problem on XJ 1992
I am thinking the same thing and I was implying once tripped, the
breaker will never be stable again.
I was thinking he tripped the new one before he cleaned up the wires
maybe?
