How to check fuel guage?? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Just picked up a 84 Chevy short wide box. Inline 6 replaced w/305, factory turbo 350. Fuel guage isn't working. Driving it home reading under half tank and stopped to put in some gas. After filling 2 gallons the tank was full and the guage didn't move. Took the dash guages out and checked the pink wire from the sending unit, it shows a little over 90 Ohms on my multimeter. I have 12V+ on one side of the printed circuit and the input from the sender but there is a third (ground?) and I don't know what it is. If I take the guage out How can I check it?

Thanks

John
