Servo Check
- With system "On" and in A/C mode, change tester lo park position. After voltmeter reading has dropped to zero, disconnect inboard electrical insulator (6-way) at serve assembly.
- Using an accurate ohmmeter, check resistance across the black and violet wires at servo (see Figure). Resistance should be between 200 and 1500 ohms.
- If resistance is not within tolerance, replace servo. If resistance value is OK, continue with test of amplifier.
