My water temp gauge is reading "0" when I have my foot on the gas yet it reads properly when at idle. I assume it's a short. Any ideas as to where to look?

loose connection in wire from sender to guage. if the wire was grounding, the guage would go to maximum. check all the crimp connections on the sender wire.

Mystery Solved

As per Cliff's guidance...I found that the black wire on the sending unit had worked it's way loose. It's located beneath the thermastat on the intake side of the motor in a pretty direct line to the fan. That explained the strange behavior...reading correctly at idle but going full to the left at revs. At idle the wire still made contact but as soon as the revs went up over 2k the wind from the fan blades pushed it away from the male lead on the sending unit. Once crimped and put back on it's all good again.

the oil pressure sender is located on the same side of the block near the rear of the engine, above the starter, might look at its connection too, lots of problems with that also.

Oil sender lead is nice and tight. Thanks for the help.
