In troubleshooting my fuel gauge, I've noticed something about the wiring I hope I can get help clearing up. My fuel gauge doesn't seem to work. I haven't performed troubleshooting with a meter yet, but some things about the wiring are confusing.
First, only the positive side seems to be attached to the sender:
I had @Roger Janeway send me pictures of his setup (we have twins) and his is the same.
Second, there's a black wire that runs along the top of the tank, wraps itself around the fuel fill hose, then is left hanging (with a ring terminal on the end) back behind the starboard stern access panel. I see a note on the wiring diagram that mentions 'Fuel Tank Ground'. Where should this wire be attached to?
What might I be missing for getting the fuel gauge to work? How should I test it? What typically 'completes the circuit' for the gauge to work?
