Good evening, two weeks ago i purchased 2017 jaguar with merc 400R with less than 30 hours on the rig. I filled the back to fuel tanks last weekend and the tanks will not read on the fuel gauge or smart craft gauge as well. the original owner never used the back two tanks. The wiring from the control panel to the starboard tank is connected but the port side wiring is not connected.

Any recommendations on trouble shooting this matter would be greatly appreciated.

The switch power one dual tank gauge and those are a yellow wire with one tank only providing the signal. They pull simultaneously and are close in draw, though slightly balanced to either side due to the anti-siphon valve in the pickups. The wire should have a signal to the dash from the wire color on the 10 gallon tank sender, and it goes straight to the dash assembly, which the switches between the chosen tank signals. Left is the under seat tank, and right is the rear tank levels.

You have an amazing ride and we hope you respect the potential and enjoy it.

thanks for the reply. I have checked all wire connections as described and still not getting a fuel reading. I Even tried connection the back port tank to see if the starboard tank sensor may have been faulty but still not getting a fuel level reading. Its defiantly puzzling for sure.

The senders have to be designated as operating, then the sending units read at the dash by an ohmeter, from there the signal goes into the dash assembly through switching and confirmation that it is feeding to the gauges from the dash in ohms also. Then it would be either the signal origin and tracking it through to the gauge, where if the gauge works on one we feel it is in the split or connection somewhere. Obviously you have some talents and are able to track some of this and it should be fairly traceable.

thanks, will check ohms to make sure I have power from the tank to the gauge.

The sender will have 5 volts of trash through the panel and some form (measurement) of ohm’s resistance which is what drives the signals.
