Strange electrical gauge issue
I have a 1989 F250 7.3 with a strange electrica gauge issue. The gauge swings HARD to the left when power is turned off and only goes 1/4 of the way to the right when power is on.. The gague use to go 1/2 to the right.
With a volt meter I am consistently getting 12.74 at the power relay as well as the battery with the engine running.
Is this normal for older trucks or ????
Thanks
Ken

even more puzzeling
It started to work like normal. Measured the voltage at the battery 13.94v. At the battery the same.
Noticed that riht after starting it is in the lower half of the gauge and then snaps to the center of the gauge and stays there.
Any ideas ????

If your truck has a speedo cable, that could be holding you up. If you can, reach around or under to the back with your hand and see if you feel the cable. If you do, feel up next to the head unit, and there should be a clip there. Push the clip sideways and the cable should release.
