If the torque element malfunctions or cannot be
calibrated, proceed as follows:
a.
Remove the compound from the potentiometers
and clean with Specification BB-F-1421 freon.
b.
Check the continuity through the signal cable
assembly and potentiometers using figure 6-9 as a
guide.
c.
If the torque element signal cable assembly is
defective, replace the cable or connector, as required.
Proceed as follows:
