fuel gauge resistor

Trying to get my fuel gauge working this weekend. It's not the wire from tank, ground wire , or sending unit. We dropped the tank & checked all that out. Read on another thread a while back about resistor on back of the gauge being a problem sometimes. What should the resistance be on it? And is the resistor on the back of the temp gauge the same thing (because I have one of those if it'll work)?
Another thing, I'm not to confident in the printed circuit sheet on the back of the whole cluster; why can't I just wire the fuel gauge up direct?

Re: fuel gauge resistor

It would help to know what your fuel gauge is doing (or not doing) right now. Does it peg out, drop to zero, move only part of the way? What's up?

Re: fuel gauge resistor

It is pegged out past full & does not move no matter how the wires are hooked up or grounded out

Re: fuel gauge resistor

I would ground the gauge directly to see if the gauge works. If it does, then see if the connection with the cluster harness is any good. My guess is that this connection is not making up well or the gauge is shot. You might just need to clean the contacts, grease them and put it back together.

Re: fuel gauge resistor

is this an original wire? you have to use the correct gauge of wire too...
