I went over and bought a voltage gauge the other day, not OEM, but a gauge just the same. The directions are for sheet, so I called just to verify installation. I was directed to wire it directlyto the battery and I should be good to go. Well I hooked it up to the factory gauge power source, so that the light wasn't on all the time. Well it ligts up, but when the car is running, I don't get a reading, the needle dosen't move. So either I have wired it wrong, (most likely), or it's defective..
Bueller..... Bueller....... Bueller.... ? Can anyone help me out?
Thanks
