When either of these cards is new, it obtains the settings from the other card. Settings are lost when both are new and replaced at the same time. Action Verify +24 V dc at J9, pin 8 and +5 V dc at pin 1 (controller card). Verify ground at pins 2 and 7 for both the card and cable. • If these voltages are correct, check the main motor cable for continuity. - Remove rear cover to access connector on motor. - If continuity exists on each wire, call next level of service. - If continuity does not exist on one or more of the wires, replace the motor cable. • If these voltages are not correct, see the "LVPS/HVPS service check" on page 2-57 or replace the controller card.
