hey all, I have a duster with some MAJOR electrical issues. I hooked up the amp gauge since I was replacing it and put the car back together. Once put back together I hooked up the battery and nothing worked. Turns out the dash does not ground out for some reason (checked with a multimeter and amp gauge showed 11.67V on both the positive and negative end) when I tried grounding out the dash with a wire, I got sparks. Any reason why this could be happening? Thanks
