"I have 3 gauges that don'
"I have 3 gauges that don't work,the fuel gauge,trim gauge and rpm.I removed the fuel sending unit,it had the thin flat piece of metal unattached to the sender screw.I put it back under the bolt and tightened it back up.I checked for resistance while I had it off,moving the float up and down watching the needle move up and down like it should.I gronded the gauge sender connection and the needle went to full like it should,I put it back together and it still didn't work.I checked the voltage on the sender wire and ground at the gas tank and I had 8 volts,I checked the resistance again on the sending unit and it was good.Any suggestions??"
