A1.01C1: Trays 2, 3, and 4 Transport motor (M18)
Initial Steps
1. Check the electrical connection at J9 on the Trays 2, 3, and 4 Controller PCA (A23).
Test the voltage at the Power Distribution PCA (A1)
1. Disconnect J8 from A1.
2. Test the voltage to the Trays 2, 3, and 4 Controller PCA (A23) on A1: 32 Vdc at J8 pins 8 to 5.
