a2. problem:
resistance does not change (assumes unit powers up
and otherwise functions normally)
Solution:
A. Check computer wire connections and continuity.
Replace any damaged wires. If wire is OK, check servo
motor.
B. Check servo motor (requires shroud removal; see
Advanced Troubleshooting, A6). Power up the unit and
adjust the resistance level at the console, watching
for movement at the servo motor. If the motor turns
but the magnet arm assembly does not move, check
and secure the mechanical components. Replace
any damaged components. If the motor does not
turn, check wire continuity and the integrity between
the console and the DC motor. If all cables are good,
replace the Motor, DC Servo.
