Anyone have better troubleshooting information than the Army TM's? I am trying to find out why the fuel gauge goes to zero. I have checked all wires to the cannon plug. I have 115 volts to the gauge plug and the ground is good. Coaxes look ok but dealing with 1964 wiring. Any other guidance would be helpful.
