Electrical Wiring At Gas Filler Cap

[Author has a 1995 Boston Whaler RAGE 15] with two wires at the flip open gas fill cap. What is the purpose of these wires? Where they should be connected? The [RAGE 15] has been converted from jet drive to outboard.

Please describe the size of the wire in terms of its American Wire Gauge and the color of the insulation.

[O]ne wire is black, the other gray, They look to be 16 gauge. One theory is that the wiring connects to ignition so that motor can't be started if cap is left in the open position. Would that make sense?

Are they paired conductors in a zip cord type cable? They're probably intended for the navigation light circuit.
Since your boat has been extensively modified by the change in power to outboard from an inboard, it is likely these wires are not in their original configuration.
I have never heard of any sort of interlock circuit involving a filler cap. In general it would be very unusual for any electrical circuit to be energized near the fuel filler cap.

Thanks for your information. All nav lights are working. I guess I'll just remove and ignore these wires . This is a great site for info . I bought the rage after reading other rage owners conversion to outboard experiences Thanks again.....

Perhaps a bonding wire to ground the filler to the engine block?

The black and gray would be for either Nav or Anchor lighting. A proper bond wire would actually be attached to the fill and would be an 8 or 10GA green wire. That is, if your Rage has a metal tank. Plastic tank? Not needed.

That's a little unnerving to have possibly live wires hanging around the fuel filler cap, an area where air is in mixture with gas fumes - an explosion potential. Get them out of there.

As Swist said. Take out your meter, strip back some insulation, and check for voltage between hot and ground. Now, turn on every switch you have at the helm, and do the same. If voltage is present, and removing them is not an option, simply heat some shrink sleeving over the ends (called "dead-ending"), and you'll be fine.

On a boat that is 15-feet long it can't be too difficult to follow the wire to discover where they go and what they're connected to.
