OK, one last time. Read this very carefully. I ask you what the GAUGE parts number is. You keep giving the SENDER part number. What is the GAUGE part number? You seem to be confused about all these simple questions. You don't seem to understand we can't fire off a bunch of "could be this or could be that" without making sure of the parts you have. Sometimes posters think they know what they are doing and get insulted by questions. But if it's the gauge or sender or something is wired wrong or incompatible parts or wrong parts and we have to figure it out from our house. We are not there. We can't trust everything because obviously there is a problem. Something is not right. We only have questions at first, not a bunch of guesses.
As Tim and I say, you may need a voltage reducer. You ask why. If you give us the gauge part number we can check to see if it's a 6V or 12V. That's why I have asked 4 times for the part number. If you are assuming this or that and making a mistake, we have to catch the mistake by searching part numbers an so on. You can't keep saying you did everything right and you have the right ohms and voltage. Someone HAS TO CHECK your work and your parts. That would be us. What is the part number of the GAUGE and where did you get it? I don't see a 12V gauge at Brothers. Don't just keep saying everything is OK, it's 30 ohms, it's 12V, it's wired correctly. People won't find a problem if they keep assuming. You are frustrated by just answering questions. This time, LOOK AT THE VIDEO.
