 Compare the measured capacitance and resistance values with the values shown in Figure 504.

 (a)  
If the capacitance value for a tank unit is out of tolerance, remove and replace the tank unit or the wire bundle (AMM 28-41-01/401).

 (b)  
If the capacitance value for the compensator is out of tolerance, remove and replace the compensator or the FQIS wire bundle (AMM 28-41-02/401).

 (c)  
If the insulation resistance value for the wire bundle is out of tolerance, remove or repair the in-tank FQIS wire bundle (AMM 28-41-09/401).
