Hey guys i recently got my hands on a freebie a voltmeter gauge from my friend
who was going to install it in his g/fs car but they broke up
and he gave it to me, I put the key in the ignition and left it there
checked a few fuses with the testlight to see what would be hot
while its off. and then i checked it with the ignition on..
i believe it was the top left one on the panel
and i ran the black hose to a ground clamp and hooked it to
the dashmount right there at the panel under the steering column cover
and i crank up,light comes on,cant change colors,and needle doesnt move at all..
Is this not a good ground connection or for some reason the one I have is screwed?

 

First of all who makes them? We need to know the brand and what color wires you have.

 

im not exactly sure of the brand the gauge face says MW
and there is 2 wires one red one black.
