				It started really simple....lights and blown fuses
			 
			All I was doing was replacing the lenses for the passenger side front turn signal and parking lamps on my 89 911 Cabrio because they were cracked.  I didn't touch the bulbs because they worked.  Affixed the new lenses and then none of the pass front turn signal or turn lights worked (headlights did as well as all other lights and turn signals).  I pulled off the contacts and the bulbs and cleaned all the contacts...replaced....Now the fuse keeps blowing.  Oh and I confirmed that the bulbs are good. What did I screw up? Does anybody have a wiring diagram that shows how to wire the turn signal behind the lens reflector....I tried the Bentley wiring diagram and it may as well be written in greek. File this under no good deed goes unpunished. | ||

			Blowing fuses means you've uncovered/created a short to ground. Pull the bulbs, put one lead of an ohm meter to a reliable ground and start testing the hot pole of the bulb sockets. When you get a reading you'll have found your culprit. Perhaps you bumped where the wiring harness goes through the headlight bucket, or it has chafed over time and exposed bare wire. Shorts can be tricky to trace, as several wires can converge at the fuse block and therefore make it look like several leads are shorted, when it's only one. You can possibly isolate the culprit by unplugging where the harness passes through gang pins, etc. The "wiring diagrams"are actually current flow diagrams, and not actual road maps of wires themselves. It takes a little getting used to, but when you wrap your head around the logic they are quite sensible. -C

			Some model years of Porsches diagrams are in fact a road-map of wires and where they go....depends on the model year.

			i dont think you need a wiring diagram. check out what have been messing with. make sure the bulbs are all the way in. look for cracked/broken wires.

			sounds like you pinched a wire or drove a screw through a wire.  It's grounding somewhere.
