69 under construction / 440

While I'm waiting on the back seat to be finished and for Al ( best Mopar engine guy ever ) to make it over to fire up this 440 I thought I would figure why this fuel gauge isn't working now that its full of fuel . After a bunch of continuity tests decided to pull the cluster out and run some diagnostic tests with the help of my son Adam. Also with the help of the valuable advice from Dana67 , thx btw. Hopefully we have it figured out and it seems to be some loose connections on the studs where it attachs to circuit board so I'll put it back together and see what happens. That cluster is a sob to get out when its in the car , air was blue with 4 lettered words lol.
