SERVICING THE AT10.1
59
Replacing the Main Control printed circuit board (A1)
For details of this procedure,
CAUTION: The printed circuit board A1 is sensitive to damage from
static discharges. Leave replacement boards in their anti-static
bags until you are ready to install them. Ground yourself before
handling the board by touching the ground stud on the back of the
door. Handle boards only by their edges.
Turn off and remove all power to the AT10.1. Remove the plexiglas
safety shield. Disconnect the battery from the output terminals. If the
optional tempco probe is installed, disconnect the leads from TB8.
Remove the harness plug from the upper left edge of the Main Control pc
board (A1), and unplug wire # 30 from the quick-connect terminal near
the upper left corner of the board. The board is mounted on six plastic
standoffs. Compress the tab on each standoff, and pull the A1 board
toward you until it clears all the standoffs. Put the replacement board in
place with the same orientation, and push it onto the standoffs. Be sure
that the board is fully seated on the standoffs. Replace wire # 30 on the
quick-connect terminal, and connect the harness plug to the board at the
top edge. Replace any optional wiring, such as the tempco probe on TB8.
See Section 2.1 for steps to restart the AT10.1. If your charger parameters
(float voltage, etc.) are different from the factory preset values, you should
program in the new values now. See Section 2.3. You should also
recalibrate the dc voltmeter according to Section 2.3.7.
Replacing the rectifier heat sink assembly (A6)
Refer to the customer instruction supplement (
) supplied with
your replacement rectifier heat sink assembly (EJ1243-00).
Turn off and remove all power to the AT10.1. Remove the plexiglas
safety shield. Disconnect the battery from the output terminals. Check
with a voltmeter before proceeding. Remove the enclosure shroud as
described in the previous section. Make sure the rectifier heat sink has
cooled, and remove the entire assembly by the front edge. Remove all
wires attached to the rectifier pc board(s) as you pull the assembly out.
Hold the replacement assembly in front of the AT10.1 (in the same
orientation as the old), and reconnect all wires removed from the old
rectifier as you insert it into the enclosure. To ensure correct replacement,
see the wiring diagrams in Appendix C of this manual or the customer
instruction supplement, supplied with the replacement assembly. When
you are done, check to ensure all wires are connected to the proper
terminals, and all lugs are fully seated. If any lug does not fit snugly,
disconnect it and carefully tighten the ears of the lug using long-nosed
pliers and reconnect.
