1988 Temp and fuel gauges don't work

[JeremyC]

Just bought a 1988 Ranger and the temp and fuel guage do not work.I replaced the guage cluster and still not working I have checked the fuses .Is there anything else I could check for? Is it possible both sending units are bad ?

Jeremy, did you ever figure out the problem? I have a similar issue. Fuel, temp, and oil pressure gauges do not work on my 1990...
