a. Performance Ckecks.
(1) Install two Accelerometers and a Magnetic
Pickup on the Tester as shown in figure 3-2.
Screw Magnetic Pickup in until it just touches
the interrupter screws. Then, back out about
one flat (1/6 turn) to provide clearance. Tight-
en jam nut on pickup.
NOTE
The Magnetic Pickup must be very close
because the small rotor diameter results
in very low peripheral velocity.
(2) Connect Magnetic Pickup and Accelerometer
Cables as shown in figure 3-2. Dress the Accele-
rometer Cables around behind the Tester so
them is no force from the cables that might
pull the cam followers away from the cam.
