I'll show you how I repaired the fuel gauge sending unit on my classic Chevy truck. The fuel gauge on the truck was showing empty, even though though the tank was full. I suspected the fuel sending unit was not working. I tested the gauge by grounding out the signal wire to the fuel gauge and then used my digital multimeter to test the resistance in the circuit. When the fuel tank is full, there should be 90 ohms of resistance between the fuel sending unit signal lead and ground. When I discovered the resistance was low, I knew I had a problem with the fuel sending unit.
This is a 1970 C-10 Chevrolet pickup truck. I welcome your comments or questions! Please like and subscribe.
