Hi guys, when I got this truck it already had gauges installed: trans temp, boost, and pyro. The trans gauge worked for awhile when I got it but now it just doesn't move anymore and I'm not sure why. The two wires coming into the probe at the transmission don't have any power coming to them and I found a box under the dash that says it's for the trans temp. There is a ground wire, grounded and a positive wire that goes into the fuse box that comes out of the wiring harness that I would assume is for the power but there is still no power for this gauge. Any help is greatly appreciated

 

You'll need to get on the gauge manufacturers site to see what you have and how they are wired. My trans temp gauge take a long time to show any movement.

 

Did you check to make sure you have power at the wire connected to the fuse box? The harness for the box may have an inline fuse that needs to be checked also.

The probe for my trans temp gauge only has one wire, so I am unsure about your type of setup.

The wire coming from the fuse box has power and that fuse is good, I checked. My gauges are iss pro and they are the factory style. If there is an inline fuse I don't see one anywhere. I'm not sure where else the power would come from for this?
