Welcome to the site from west Michigan.

Nice project!

WELCOME aboard, Bill!

As a couple Members have noted, you have a GREAT looking engine compartment on your Mustang.

When you get the opportunity, please take some time to go through the different Forums and don't hesitate to post up on any thread which interest or otherwise bring to mind additional questions. I also encourage you to take a look at the attached thread which provides specifics on our Weekly Fun Question exercise.

Bill,

I'm with Don on this one - I think you are going to have to go back into the main gauge cluster. You can certainly check the sending unit before you do however, because it is a heck of a lot easier that ripping back into the gauge cluster. One question though - do you have the optional 3 gauge mini-cluster (oil pressure, temp, and ammeter) ? If so, do the temp and oil pressure gauge still work? If they do, that means that your 5 volt constant voltage unit (CVU) circuit is still intact. If you don't have the gauges or if you do and they also do not work, you may have cracked the copper trace from the CVU to the fuel gauge terminal during your earlier maintenance action. If you had the main cluster removed and did not support the CVU, it tends to dangle and put pressure on the fragile 40 year old copper traces in the printed circuit. I found this out the hard way in 1980. I still have the evidence with me today and have snapped a photo. The CVU is in the upper right portion of the photo. If you follow the traces in the PC just to the left of the CVU you can see where mine cracked because the CVU bent backwards when I removed the gauge cluster. After re-installation, my fuel gauge did not work - neither did my temp and oil pressure gauge because they require the 5 volt source from the CVU to operate. The fuel gauge is connected directly to the printed circuit layer (no wires from the CVU to the gauge or from the sending unit to the gauge - only the conductors in the printed circuit layer). The sending unit signal comes in to the PC on the main harness. That's why I don't believe you have a loose wire. In my case, I had to find a replacement printed circuit mask in the junkyard (an easier task 30 years ago). Anyway - it is something to consider.

Welcome aboard from Wisconsin. That is an awesome looking car and engine bay.

Bill,

Did you find out what why your fuel gauge stopped working? Not sure if you saw my earlier post about the issue I experienced with my fuel gauge years ago. I am interested in knowing what caused your problem.

Steve, thanks for the advice and the time you put into it. I've counted out the sending unit and will check the gauges again this weekend. I was really careful with the guage unit when I pulled it. I'm going to pull it again and see if it's what you've suggested. I tested all the bulb lines with a volt meter but forgot the spedo....great advise..no I wish I had the (3 gagues), but mine is a plane jane 71.

I''ll letyou know.

Thanks again

Bill
