Hello,
My fuel gauge always reads full. Here's what I tried; I disconnected the brown wire connector in the trunk which goes to the sending unit. I'm seeing 12V on the side of the connector going back to the fuel gauge. Is this correct. How can I check if the problem is the sending unit or the fuel gauge. Can I connect a resistor from the brown wire connector (which has 12V on it) in the trunk going to the fuel gauge to ground. I'm thinking maybe the needle should move? This problem just started, it's worked fine for years.
Thanks,
John
