Erratic fuel gauges

[edasmus]

Hi Pete,

My name is Ed Asmus and after reading this thread it sounds like the problem I have in my C337G 1973 model. Erratic fuel guage readings began on my last flight last week and my shop is 99% certain the problem is in the "Fuel Control Monitor" also known as the "Signal Conditioner" part number C668004-0102. My mechanic re-soldered the female plug that connects to the control monitor with no improvment. Is it possible to re-solder the pins on the male plug that is attached to the control monitor board? My mechanic thought it could be done seeing as overhauled ones can be purchased so somebody knows how to do this. It looks like to replace the entire control monitor unit would be $1200+ which would make me sad knowing that somewhere there is a simple lose connection. How do you remove the male plug from the control monitor board? Any suggestions?

Thanks Ed
