Traveler Posted October 13, 2022 Share Posted October 13, 2022 pulled the dash to replace the pc board and found the possible cause of lighting issues and the gas gauge malfunction, pc was in worse condition that I anticipated and I think I may have found the problem with the gas gauge as the end of the trace might have been pulled away from the plug that inserts into the pc board 2 Quote Link to comment Share on other sites More sharing options...
Traveler Posted October 13, 2022 Author Share Posted October 13, 2022 the trace in the circle is for the gas gauge I hope it clears that up when I reinstall it Quote Link to comment Share on other sites More sharing options...

stangeba Posted October 16, 2022 Share Posted October 16, 2022 Is the dash "grounded" correctly / fully You could add an extra ground wire, that you know is truly grounded, for testing purposes. Here are some pictures I have from my 71 with the optional gauge package. I forgot to hook up the ground wire attached to the parking brake assembly and had some problems. I also remember being worried the power spade, for the clock, could "touch" the printed circuit and receive power or a short if I didn't add some black tape to insulate it. I also remember a problem people have had if the wrong headlight switch is used. Mine has 7 pins. some replacements do not. Again, for my 71 NO A/C Good luck! 1 Quote Link to comment Share on other sites More sharing options...
MC1of80 Posted October 16, 2022 Share Posted October 16, 2022 X2 to what stangeba said, check the grounds. Sounds like a grounding issue now. Quote Link to comment Share on other sites More sharing options...
Traveler Posted October 16, 2022 Author Share Posted October 16, 2022 from your pictures I did miss one ground the single wire to the instrument cluster, and I’m not sure of the emergency brake that I will have to check, I did tape the terminal on the clock for me everyday is Saturday except Sunday hopefully I’ll be motivated enough to get it done tomorrow ps- the part store’s clock movement is the same as oem (second had stops after moving forward one second) the only differences are the lack of the clicking noise and the device that locks the adjusting nob to the stem is black not silver that and it’s quartz Quote Link to comment Share on other sites More sharing options...
