Generator inspection
Generator coil resistance
Remove the left side cowling. Refer to “exterior parts removal and
installation” in section 9d .
Disconnect the generator coupler (1).
Measure the resistance between the three lead
wires.
If the resistance is out of specified value, replace the
...
Fuel level gauge inspection
Inspect the fuel level gauge in the following procedures:
remove the fuel pump. Refer to “fuel pump disassembly and assembly” in
section 1g .
Measure the resistance at each fuel level gauge in
float position. If the resistance is incorrect, replace
fuel level gauge with a ne ...
