Relays
The superstructure has 7 relays (Table 3-4) (Figure 3-3 and
3-4) which control many of its functions. The relays are
located on the superstructure relay panel assembly
(Figure 3-4).
When any relay coil is energized, its contacts either close or
open. This allows power to go to or be removed from the
related circuits. For any relay coil to energize, the battery
must be connected.
Table 3-4
The coil of the accessory relays (K1 and K2) are energized
when the ignition switch is in the RUN (1) or ACC (3)
position.
The coil of the ignition relay (K6) is energized when the
carrier ignition switch is positioned to START (2) or ACC (3)
and held energized when ignition switch is released to RUN
