Hi Roger,

Just went through this with my '39, so not sure if yours is same, similar or totally different. At any rate, on mine, the car had been improperly hooked up negative earth when I bought it and my gas gauge didn't work. I dropped the tank and cleaned up the wiring and refreshed the ground. After that, it 'kind of' worked but the needle flicked around and eventually it just quit. It sounds like you have your dash gauge out and have wired it properly, so based on what you're saying, it would sound like a bad sender unit. One thing I wanted to mention to you was, I went through KM Lifestyles for a new sender and supplied them with all the info on my car. Then when I received the unit, it reported backwards. They had supplied an Atwater Kent sender and my car was Stewart Warner equipped and, for some reason, the ohms values are reversed on the two brands. They did rectify the problem and remade the piece with SW compatible components and I received the revised one back yesterday. Once it warms up a bit, I'll be dropping my tank and installing it, but in the meantime, bench testing confirms it is now correct. Something worth clarifying when you go to get yours repaired/replaced. Chris.
