In looking at the wiring diagram for your particular car, and since you have 12v at fuse #1 with the key off, you should have 12v at the BATT terminal with the key off, which is B on my picture, but you don't. One of the two brown wires on terminal B goes straight to fuse #1 and the other brown wire goes straight to your light switch. Try pulling fuses 6, 7, and 8 and leave them out. Then see if the car will start normally and behave normally, electrically, except for the fact that you have no lights. If it starts and runs, then try turning the light switch on and off, hit the hi-beam switch, and see if anything dies, etc. If everything seems ok, put fuse 6 in and repeat, if that's ok, put in fuse 7 and repeat, and if that's ok, put in fuse 8 and repeat. It shouldn't survive that test and I'm mostly interested in which step kills it.
