INSTRUMENTATION 5.3 Testing the Fuel Sender 1 With the ignition switch off, connect an ohmme- ter between the positive and negative terminals of the fuel sending unit. (fig. C306) 2 An ohmmeter reading of 50 to 500 is normal. A read- ing higher or lower means a faulty sender and will need replaced. C306 Replacement 1 Make sure the fuel level is below the point where the sender unit is mounted to the fuel tank, just behind the right lift cylinder (fig. C2465) Drain the fuel tank if nec- essary (fig. C2467). 2 Remove the 2 wires connected to the fuel sending unit. Be sure the ignition switch is off.
3 Remove the 5 screws retaining the sending unit to the fuel tank and remove the sender noting the orientation to the mounting holes. 5 Install a new sending unit and gasket. Use gasket sealant on both sides of the gasket. Torque the mounting screws no more than 20 inch / lbs. 7 Connect the sender wires taking care not to over tighten the nuts and stripping the studs. Green wire is ground. Sender unit 5 C2465 Fuel tank drain Testing the Hour Meter The hour meter records the number of engine operating hours. To check the hour meter, remove the 6 bolts retaining the dash panel.
Using a 12 volt test meter, connect the positive lead to the positive terminal of the hour meter and the ground lead of the tester to a good ground. Turn the ignition switch to the “RUN” position. A reading of 12 volts means the hour meter is defective. No voltage reading means there could be a problem in the wire running from the “ACC” terminal on the ignition switch to the positive side of the hour meter or a defec- tive ignition switch.
