Dash back lighting

[Boogieman]

Hi Guys!

I seem to have a problem I hope some one can shed some "light" on.

I have re-assembled my dash on my '68 Targa. After a complete restoration and when I
put the gages back in (with the correct wiring, as I labeled and created a diagram for
each upon disassembly) I have no back lighting in the fuel, tach or the speedo. The lights
in the clock and temp gage do work! I have not screwed the brackets back in on the
tach yet. The blinker lights work, the break light, red, green, high beam and parking
lights all work! The bulbs seem to be O.K. although I did not check the all. Does this
puzzle any one else? I have not checked the voltage with my meter yet. Does anybody
know if all the back lights have the same ground?

Does anybody have any suggestions?

Any help would be much appreciated.

Thanks in advance!

I'm not too sure about your 912, but my 356 and 914 suffer from problems with the lights on the gauge. The first thing I would check would be the voltage on the wire. If there is 12V going though there, then you need a better ground to the gauge. This has been my problem with my car. I have run separate grounds to the gauges when the lights have flickered on and off...

Hope this helps,
