You can also read the voltage at the sensor, which may be easier to get to than the back of the gauge.
Won't the sensor read 0-12v? Only after the voltage goes through the regulator would it read 0-5v, right? If so, then you have to read it at the gauge.
If it reads more than 5v at the gauge, then the regulator has been bypassed. If this is the case, then the 0-5v gauge would be maxed out when the temp sensor was sensing the middle temperature (normal running temperature). Normal running temperature should be sending about half of 5v to the gauge, or about 2.5v. At least all that makes sense to me.
