Fuel gauge not working after cluster work, need advice please!
I've been working on my instrument cluster (thanks for help with the parts mil1ion!). So, I put everything back together and everything works except the fuel gauge, needle doesn't budge. I tried two different circuit boards with the same result. It's been a couple of months since I took it out so maybe I'm forgetting something. The fuel sending unit is electrical, right? Doesn't the gauge get its reading from the circuit board?
Thanks for the help,
Shane
One other thing, it looks like I broke the retainer on the speedo cable when I removed it. All that plastic was so brittle it must have went with the cluster back. How can I fix this so that the speedo cable will stay plugged in?

Yea it gets it's reading from the board, mine is an orange wire that runs from the circuit board connector over to the left up the pillar and back to the top of the tank.
The easy way to check it is to remove the wire on the top of the tank and ground it. The guage should read full, otherwise bad guage or wire.
Then check the ground from the top of the tank to the frame/body, these can rust out sometimes.
If the ground is good AND the orange wire grounded makes the guage read full, pull out the sending unit and look for gas in float or broken contact inside the little box at the top. You can open the box with screwdriver and pliers but use care not to break it. One of mine had a broken contact and bad float.

I used a small nail to hold mine in, it has a little bump on one side that fits into a slot in the cable. A small nail wedged or taped in there should hold, they usually don't have anything pulling on them anyways.
You can also try to see if the *gauge will pin to past full* by grounding the gauge signal wire.
