temp gauge problems no voltage at sending unit
I've read some treads on the temp gauge sending unit but I'm a little foggy on where to look for my problem. I just purchased a 2000 F250 7.3, temp gauge not working. It has a new sending unit. I read some threads about the voltage at the plug but I have no voltage on either side of the plug. The way I understand it red/white wire goes to the battery. Is there a fuse between them and which one is it? and if fuse is ok is there a cronic problem that someone might know of that I can look for? thanks!

it's an automatic, so I should be getting 12v at plug, correct? which I'm not and I'm trying to figure out the best way to figure out why.

I would think the issue is originating at the cluster or in the line from the cluster to the sensor. Perhaps and open over time has occurred? |
Ok so my best bet is to start at the cluster and try to trace this thing back to the plug, sounds like fun. Thank you Thomas I'll let you know if I have any luck.

I wanted to send an update because I know I'm probably not the only one to run into this. I decided to start at the temp sensor so I went to Ford and purchased one. He sold me the 3F1Z-12A648-A. When I took old one off it looked like the new one so I installed it, put plug on, but did not fix the problem. I noticed the plug wasn't seated all the way down on the sensor so I pushed really hard and cracked the damn plug (pigtail). after looking at it, I could the grooves on the sensor and the grooves on the plug were not the same. Evidently the guy I purchased the truck from had the same trouble since the old sensor looked like the new one I purchased. So after some time on the phone with Ford dealer I purchased F65Z-10884-AA Temp Sender and the pigtail is the WPT-1325. These are the correct replacement parts. Good luck........

Temp gauge works fine now!

Reps for posting up the part numbers! That will help somebody down the road.
