I seem to be post happy, this Monday morning. The courtesy lights on my 71 GTV Euro have never worked. Fuse 1 immediately blows when an 8 amp fuse in put in. So my neighbor(an auto electrical engineer) and I tried to track down the short. We were using the wiring diagram supplied by papajam, titled 1750 GT Veloce Series 2. Here is what my neighbor said:
"Your door switches break the ground connection to the dome lamps.
The dome lamps however, are already grounded from the housing to the roof.
The dome lamps only have a single power lead from the fuse.
In order for the dome lamps to function with the existing door switches, there would have to be an extra wire for the ground. The ground wire from the lamps would go to the door switches."
Curiously enough, he happened to see a wiring diagram for a 1750 Berlina in my Autobook, that he said more resembles my car's courtesy light wiring.
Does any of this make sense to anyone? I am embarassingly inept at car electronics(my previous posts support that)!
