 EXCITER IN A STRAIGHT LINE. IF LATERAL FORCE IS
 PERMITTED, THE ENDS OF THE CABLE CAN BE DAMAGED.

 (a)  Lubricate the threads of the coupling nut at the igniter plug end of the cable (3) with antiseize compound.
 NOTE: Do not apply a large quantity of antiseize compound to
____
 the coupling nut threads.

 CAUTION: DO NOT TWIST THE CABLE WHEN YOU TIGHTEN THE COUPLING NUT.
_______
 DAMAGE TO THE CABLE CAN OCCUR.

 (b)  
Connect the coupling nut to the igniter plug.

 1)  Make sure that the coupling nut is sufficiently loose to permit the cable (3) to move freely.

 (c)  
Lubricate the threads of the coupling nut at the ignition exciter end of the cable (1 or 3) with antigalling compound, FelPro C300.

 NOTE: Antigalling compound, PWA 550-3 is optional to
____ FelPro C300. Do not apply a large quantity of compound on the coupling nut threads.
 (d)  
Connect the coupling nut to the output connection of the ignition exciter. 1) Make sure that the coupling nut is sufficiently loose to
