Hey all, I recently (last week) replaced my dash pad on my 67 with Rally Gauges, and part of the installation was removing the gauge pod assembly. It all came out fine, and while it was out I decided to take the time to disassemble the assembly and clean everything good. I did not mess with the printed circuity on the back, but I did take the clear lens out, and removed the gauges and replaced all the light bulbs while I was in there. Well now that the new dash is on, and everything is back together, my Fuel gauge no longer registers (it goes straight to the full side and buries the needle) and when I put on the park lights only, the right turn indicator on the gauge illuminates. Is this a bad ground? I noticed a small gauge rod running from the back of the assembly, to the high beam indicator, and finally to a mounting screw location where it bolts to the metal dash part. Is this the ground? Anyone else ever have this issue? I have played with the electrical connector at the back of the pod, and it is nice and tight, and all other lights and indicators work as they should. I am not sure if the other gauges are working or not as I run an external oil pressure and water temp gauge, but the fuel gauge has never had any issues until now. Any help is greatly appreciated, and I can take some photos of the ground rod if anyone is confused as to what I am talking about. Thanks!!!

Yup bad ground , my 69 did all sorts of odd stuff until i "went overboard" if there is such a thing i grounded everything i could and made extras, waaaay better lights are brighter , gauges dont fluctuate. clean the gounds contacts good on the metal dash frame.

Yes, that rod is the ground. Do you have that upper center gauge pod screw installed? Maybe try wiggling/turning that screw and see if it clears things up. If so, go over that connection and make sure it's solid.

X 3 (bad grounding on that upper center screw)

Thanks guys!! I was leaning toward a bad ground. I'm going to pull it all back out and add an additional ground to the pod.

So I have taken everything apart, and even ran my own wire and traced the grounding wire and still having issues. It is obviously a bad ground because the lights flicker, and the turn indicators come on and off when I mess with the grounding wire. Are there additional grounds I can somehow add? Everything worked perfectly until I removed it for the dash. Now I'm kicking myself for taking the assembly apart to clean it.

Well after installing and removing the gauge pod prob 30 times (trying one new thing at a time)....problem is still there. I added grounding wire to the rear of the metal pod and no difference. I even wrapped the original grounding rod with copper wire, and made a new connection to the dash, and again no difference. I'm starting to think its the speedo mount somehow, cause that's all I removed and there are two rubber grommets on the bolts. Grommets look good though and removing the bolts and re-installing them had no difference. Any thoughts guys and gals? i even checked the plug and connections there, and everything seems good and tight and I added dielectric grease to all the electrical connections to ensure a good connection. Its like a whole different assembly and it makes me want to use a BFH on it.....

i actually wirebrushed every connection i made to ground. I added like 5 extra grounds from the dash assy. to a good clean ground. i added grounds where the film is in contact with the housing. tons better.
