Hello everyone. I have a 1976 911S Euro experiencing electrical issues. I will number them for reference. 1) My left tail light doesn't work. When I remove the right tail light, the left one comes on. Since my battery is good and the bulbs work, I am thinking that it's likely the switch or a short in a wire. If so, where is the switch located and how do I test it? 2) My temp guage isn't working either. I have no idea if it uses the same ground as the tail lights or not or even where its ground is located. I put in a new temp switch and it didn't help. 3) Finally, the fuse holding the tach wire is on the same wire as the sunroof. It keeps blowing. I changed the sunroof to a different fuse (blower fuse) and the sunroof now works. The tach works even with the blown fuse. Weird. Any help would be appreciated. Let me know if you need pictures. Thanks in advance.

 

I think you posted this in the wrong subforum.

 

Moved it to the 911 forum -- I think that's the right spot...

 

Oops. Sorry. Thanks.
