Temperature sending unit not working?

[greg82255]

Hello

So I just finished doing a 2 to 4 barrel swap on my chevy 305. I fired it up, everything runs great, but I noticed that the temperature gauge was not reading anything. I tried cleaning and tightening the connection on the sending unit while it was running, and still no reading. I then tried tightening again and accidentally touched the sending wire to the flat surface on the sending unit with a screw driver, and this moved the gauge from no reading to maximum. I assume i just completed a circuit and that got the gauge to move. Is my sender bad? I just installed a brand new one last year. Could something else be going on here? This seems very simple, but I need the temp gauge to work.. need to know if the engine ever overheats.

generally if your gauge is not working and you ground out the lead and it goes to the high side , your sender is baddd !
