I am restoring a 20' Haterus. The gas gauge is not working. Having trouble finding the wires to connect. To get to the unit, I am told I have to remove the helm. Any thoughts.

Good luck with the restoration.
The first step to trouble shoot a fuel gauge not working is to locate the sender unit which is typically at the aft end of the fuel tank. There should be a way to access that spot. Usually there is a deck ( or pie) plate over that area. There should be two connections for the sender but for now we are looking for the signal wire. If Grady used their standard wire colors way back, the signal wire will be pink. unplug that wire at the tank sender. Your gauge should read empty. Now run a wire from a known good ground like the black battery terminal and touch it to the end of the disconnected pink wire. Wait a bit and see if the gauge moves. It should eventually read full.
If those two tests work, most likely your sender is bad ( likely) or the ground at the sender is bad. If nothing changes with the above tests, you will need to get to the back of the fuel gauge and look for the pink wire. One step at a time
On another note, I am not sure what remove the helm means. I have never seen a Hatteras so I can only go by what can find on the internet. Isn't that a cuddy cabin style of hull?
Can you post a photo of the helm area and the space behind the helm in the cabin.

Thanks for the response. It's a center console walk around. No cabin. I will try and track down that wire and see where we get.
So you don't have any access plates? Do some more research and/or contact Hattera and see if they can give you the diagram of the tank. That should show where the sending unit is relative to the tank dimensions. Can you see ANY part of the tank from ANYWHERE in the boat? Use a snake camera to find the sending unit.
After finding the location, cut a hole in the floor for an access plate.

What is the boat model again?
There is no Grady Haterus. Is it a Hatteras? What year?
There is another thread on a 204 Hatteras restoration and that is a cabin boat
1978 Hatteras 204-C Restoration
Hello Grady owners, I am new to this forum and appreciate your Grady guidance! I am in the process of restoring a 20' 1978 Hatteras Overnighter. This is my first big boat project and I am really enjoying it. For a 44 year old boat, the hull is in great shape. She seems practically bullet proof...

As far as I know from the Hull number it is a 1978 20.4 Hatterus. It is a walk around helm, no cabin. Hull number is LTNK0464M78J

Like Seasick, I've never heard of a "Hatterus" boat, either. I assumed you just didn't know how to spell "Hatteras". I suppose for this conversation it's a moot point - but, generally, it's important to be accurate.
Walk around helm... do you mean a center console?

It sounds like GW did make this boat. Problem is confusion identifying what type of boat it is to cross check to what GW built.
Get some photos of the boat put up here. Also photos of the deck and pie plate access ports.
I doubt it's a complicated as this thread is evolving into. This is an old boat , improperly id'ed, little documentation and poor description of what we are dealing with. Help us help you!
