Expected Results. Voltage is between 22 VDC and 27 VDC.
If voltage is as specified, data link connector is currently receiving correct voltage. Proceed to step 6.
If voltage is not as specified, data link connector is not receiving correct voltage. Inspect wiring and fuses
to connector. Repair or replace wiring (WP 0022 00) or batteries (WP 0077 00), as required. Send machine
