I mentioned in a previous message I have installed a new 12 v fuel gauge. It is marked 12v on the back if the gauge. I've connected the terminal marked "ign" to the ignition. I connected the terminal marked "sender" to the fuel sending unit at the gas tank. Ok now I connected the ground wire from the sending unit (on one of the screws that you attach the sending unit to the tank) to the frame for a good ground. I don't think I need a voltage reducer because its all 12V - Gauge and sender. All I'm asking if I run a test where I disconnect the wire at the sending unit, the gauge goes to full max. Does this mean I need a sender?
