Fuel gauge dead

Recommended Posts

Posted (edited)

Help the fuel gauge on my sig 350 2006 stoped working. This is the connections to the switch that I choose which tank to show. If someone withe the same model would be so kind and check ther switch/ breaker and se if something is missing. Or if someone have other suggestion how to check cables  

 

thanks for help  Par

That looks like it may be missing a wire. The yellows are likely grounds, the blues are the signals from your fuel senders, and the red is +12VDC for a backlight in the switch I assume. The switch will simply switch between which blue wire is connected to your fuel gauge. I’m not sure, but should there be a sixth wire which connects the signal to the fuel gauge? Maybe the red isn’t a backlight and goes up to your fuel gauge  

You should be able to disconnect each wire and test it with a multimeter to confirm my assumptions. The voltage you find, or don’t find on the blue wires can also help diagnose whether it’s a fuel sender issue, dead switch, or dead fuel gauge.

Thank you. Finally found two loose wires. So problem solved
