POT AR,M MIGNMENI' PROCEDURE
If you have not already done so, determine if the controller cable is defective (see
Table 6-1). If the cable is not defective, continue with the following steps.
Use Figure 6-4 as reference for steps 1 through 3.
1)
Disassemble the con~oller and remove arm from wiper shaft on pot.
2)
Adjust wiper shaft on pot so that reading between terminals 62 and #3 is
5K -20K Ohms,
3)
Position arm on wiper shaft as shown below; position A.
Figure 64.
Pot and Arm Assembly
4) Reassemble the controller (refer to Page 6-10, CONTROLLER
DISASSE MBLY/ASSEMBLY.
5)
Move the controller joystick m position 1 (refer to Figure 6-21. Use an
Ohm meter to determine the pot readings through the cable (cable
connector Pins 11 & 9 and 10 & 9). The pot reading should be no greater
than 50K Ohms.
6)
Move the controller joystick to position 2 (refer to Figure 6-21. fhe pot
reading through the cable (connector Pins 10 & 9 and 11 & 9) should be at
least 430K Ohms greater than in position 1.
