J502.

3. Turn the machine on.
4. 24Vdc on positions 6, 17, and 19 of the cable

connector (LVPS/HVPS).

5. If voltage is correct, then check the continuity in the other

conductors of the cable. If the cable is good, then turn the
machine off, and check the connectors to the controller board.

6. Verify that pins 10, 12, 14, 16, and 18 on both the cable and

the card connector are grounded.

7. If grounds are not correct on the cable, but the cable passes

continuity otherwise, then check the LVPS/HVPS.

8. If the grounds are not correct on the engine board, then

replace the engine board. (Check with one probe on the
connector pin and the other on the card’s ground plane found
at each screw head.)

Engine board assembly

Engine board voltage outputs
Turn the machine off, and plug the LVPS/HVPS cable into J502 of
the engine board. See the wiring diagram which identifies the
output voltages and grounds for a good engine board.
Turn the machine off before plugging or unplugging any
