Curtis - '97 Targa

My instrument lights went out last night. I know the fuse is good because it shares a circuit with the license plate light which comes on.

I fiddled with the relay (R24) pulled it and reseated and the lights came on for about 20 seconds, then went out again. Sounds like a bad relay, so I ordered one today. I won't have it for a week or so and would like to jump the terminals to get instrument lights between now and then. I can't decipher the wiring diagram to understand what terminals to jump. Can someone explain it to me, please?

Thanks

Gert

Connect 58(green) with 58d (green/blue).
According to the wiring diagram it should be connection #4 and #7.

Thanks Gert. I appreciate the help.

What on the diagram did you look at to determine the answer?

Gert

58: comes from the light switch
58D : Goes to the illumination.
Also, the 993RS didn't have this instrument illumination adjustment, so if you look closely to your relay drawing, it shows a jumper inside the relay "Only RS".
According to the electrical drawings of the '97 the jumper should be placed between pin #4 and #7.
If you want to be sure, check the colors of the wires. The jumper should come between the green and the green/blue wire.

Thanks again, Gert.

I rigged up the jumpers and now have instrument lights. This will work great until the new relay gets here next week.

I just debugged the same problem on my 1995. The Relay is in a different place on my car so I add a link here as a cross reference. Once I located the "relay" it was easy to test the solution by jumpering 58 to 58d. I don't have a replacement relay yet, so there's a small chance the problem is somewhere else - like in the dimmer switch - but I'm 95% sure it's the relay.

Part number: 964.618.103.00

BTW - the dimmer part number, for future reference is: 964.618.104.00

Thanks for this post, BTW.

You can always pop the relay open, clean the contacts and put it back in. If you want to get fancy you can buff the contact points with 1500~2000 sandpaper.
