Hi Mark. Both gauges are GM originals as far as I know. One is in the console and one isn't, anyway to make sure, I can check the one that's out? Is there a breakdown, schematic drawing, picture or something I can compare how these are put together? The problem I have is when I install the resister it goes to full now that you say that. I've been really curious about it. I was told several times the resister should be there, but like I said when I install it the needle goes to full and stays there. How do I check the resister? Just touch the OHM meter + - leads to the mount holes and see what it reads correct?
Thanks. I really don't want to fool with this again this year. What about the sending unit? Maybe bad?
