voltmeter maxing out issue

[vdragonmpc]

I have an odd question. I have a volt meter swapped into a dash. It maxes the second I turn the key to on.

What am I doing wrong? I have tried the ground wire but that made no difference.

Im on a 91 GTE. Its odd that it does that even when I know the voltage is low.


Thanks.

I also have no tach. I was told it was a gte dash cluster but the tach doesn't move and the voltmeter that is installed maxes when I turn the key on. (temp guage goes way up too) It seems like there is a crossed connection somewhere.

You need to use a cluster from the same year car. For the tach you need a turbo tach for turbo engine but if the cluster is a different year you need to use the same year cluster and swap just the tach.

I swapped the tach and its working. The oil, temp and gas seem to be behaving. The volt guage I am going to try to swap out as this one maxes on a 9v battery test.
