Wiring Help

[Bobby23]

RC, the senders and guages I have worked on have ignition or some 12 volt source, light, and from the guage the sender wire should go to the sender and back to the ground on the guage. The sender in a tank is a resistor which provides more or less voltage depending on tank level. If that does not work let me know and I will tell you how to trouble shoot to see if you have a bad guage or sender.
