Engine Temp gauge quit working; Testing The Temp Sensor

Engine Temp gauge quit working last weekend.

I'm pretty sure it's the sensor, as I have disconnected and reinstalled the battery terminals, and when I turn the ignition key to the on position, the gauge pegged then went back to zero.<O</O
<O</O

I searched the forum, and found a post on how to test the sensor, but cannot locate again.<O</O
<O</O

Am I correct that my gauge is not the problem, probably the sensor?<O</O
Does this gauge monitor water temp (sensor above water pump)?<O</O
Can anybody tell me how to test the temp sensor (keep in mind I'm not an electrician?)
Does anybody know the part number for the sensor?<O</O

Any pictures would help.

Does anybody know how to test the sensor. I would imagine ohm it out but what should the reading normally be?

Found the post; Finally.
Pic looks like it came from a service manual? A bit blurry.<O</O

https://www.ford-trucks.com/forums/783231-coolant-temp-sensor-info-needed-gauge-not-working.html<O></O>

Ordered the sensor for about $15, assuming I've got the correct one from local dealer.
I will post the correct part # once I verify.<O</O
