Gas gauge - sender
Happy pre Thanksgiving..
I just replaced my fuel tank due to a leak. While at it, I decided to change the sender (although the former one was working). I tested the new sender prior installing in the tank and got 1 ohm at the low end and just over 90 at the top end. I put everything together and the gauge doesn't move.
I checked the ground from the sender to the chassis and the pigtail connection in the trunk and all seemed fine. I then disconnected the pigtail and turned the key on and the gauge needle goes past full. I then grounded that same lead and the gauge goes past empty as it should. I then checked the resistance between the lead going to the sender and ground and got about 24 ohms. It think it has about 5 gallons in the tank. I checked the power from the pigtail to ground with the key on and get about 10 volts. When I put it back together, the gauge still doesn't move.
i am stumped. Any suggestions are appreciated.
