— If the voltages are not present, replace the A9 Interface Board.
— If the voltages are present, proceed to step 9.
• If A9J2-4 is not ∼12V, measure A9J2-3.
— If J2-3 is ∼12V, replace the A9 Interface Board.
— If J2-3 is not ∼12V, go to step 9.

9. Refer to Figure 1-15. Using the voltmeter measure A3J6-4.
• If A3J6-4 is ∼12V replace the W1 ribbon cable.
• If A3J6-4 is not ∼12V go to step 10.
