2001 Bayliner - Fuel Sender Green/Yellow wire?-gctid823808

[DJ5S]

Hey guys - new here. Just got a 2001 bayliner capri. The fuel gauge is stuck in full. I took a look at the fuel sender cap on the fuel tank and there is a green wire with a yellow stripe that looks like it is supposed to be connected to a ground screw somewhere but it's not connected to anything. Does anyone know where to connect it or if this is the issue with the gauge being stuck in full? Thanks!

Green wire is ground from a little aluminum tab sticking up near the sending unit,-- grounds to the engine block.

Thank you so much! That tab must be missing. I will try to find it tonight. So ground it to the engine block? If I do this, do you think the gauge will start working again? Really appreciate your help on this, I will let you know how it goes

A green wire will be a bonding wire. It'll usually be connected to the metal fuel tank via a tab welded to the tank near the fuel sending unit, the tab has a screw that secures the green wire to it. As Fritz said the green wire will be connected into the negative side of the 12 volt system somewhere in the engines wire harness or engine block.

thanks for the help. i can't seem to find the tab. here is a photo of the way it is wired and you can see one of the plastic zip ties is snapped and the green wire is just floating. i have no idea where to wore it because it is so short and i can't find any tabs nearby...

Probably saw my reply on ya other thread. No bond on the plastic tank, the sender could be bad, had one fail showing 3/4 full but it was almost empty inch:

If your 01 is like my 99 it has a plastic tank, no ground needed.

Can be a couple things.

- a stuck gauge

- stuck/bad sender

Hopefully the second one, I was able to get mine reading properly after filling the tank with fuel and dumping in a couple cans of Sea-Foam

Even with a plastic tank the sender will still require a negative bond (Ground ) for it to work!!!

The sender is a resister and needs to have a path to ground!

The bonding wire is there to prevent a charge from building and not to be a ground or negative. Yes the sender needs a negative return as well as the sense wire that goes to the gauge.

Correct, should have been more clean in my post

[DJ5S]

Do you know where I should attach the green/yellow wire?

since you have a plastic tank no need to attach but it would not hurt to install a ring lug on the wire and screw it down using one if the outer fuel sendor screws. Basically same as the negative wire.
