Battery disconnected (Para 2-62)
Item 1)
Materials/Parts
Self-locking Nut (App F, Item 62)
Tags (App E, Item 16)
NOTE
This procedure covers one of the power resistors. Replacement of the other two is
similar.
a.
REMOVAL. Refer to Figure 2-113.
(1) Remove panel (1) and open door (2).
(2) Tag electrical wiring (3).
(3) Remove nuts (4), lockwashers (5), flatwashers (6) and electrical wiring (3) from resistor (7).
(4) Remove self-locking nuts (8), screws (9), flatwashers (10) and resistor (7).
b.
INSTALLATION.
(1) Position resistor (7) on unit and secure with flatwashers (10), screws (9) and self-locking nuts (8).
NOTE
Wire numbers are stamped on each electrical wire. This information, in
conjunction with data on FO-1 and FO-2, 200/600 GPM Pump Wiring Diagram, may
be used to connect wires if tags are lost or illegible.
(2) Position electrical wiring (3) on resistor (7) as tagged. Secure electrical wiring (3) with flatwasher (6), lockwasher
(5) and nut (4).
(3) Close door (2) and install panel (1).
