the wires are 10 ga. so that is a serious draw.

Re: Headlights problem on XJ 1992
Here I am.
I 've just checked everything again and like Mike said, on left inner fender
I found ground connections - three of them, little lower down just near left
headlight - a bunch of connections and removed all of this, cleaned
everything (with good old WD40) and tried to drive around almost half night.
Nothing happened. Seems OK.
Now I remember after one hard day for my rig somewhere in very muddy
terrain I washed Jeep underneath and engine also (mud was everywhere), maybe
some connections were corroded or, I don't know... I'll see next few days
what will be but seems that everything is fine.
One more question: This wire mesh strap which is hanging from firewall
should be connected somewhere on cylinder head? I found it just hanging, not
connected. Now it is temporary bolted on intake manifold. Probably previous
owner forgot to connect again after doing some repairs. Seems to me like I
can connect this back on bolt which holds fuel rail. I couldn't find any
other ground connection from engine to chassis, strange.
Anyway, thank you very much for advices, many greetings from far Croatia.

That's your engine ground strap. Without it your engine gets it's ground
through the drivetrain and that can cause all sorts of sensor problems, rough
idle, etc. It goes back to the block. On the 93ZJ it uses the same bolt
that holds on the ignition coil, not sure about the 92 XJ.
