Section 5
Relay Controller
5-I. DESCRIPTION
All generator set functions are dependent upon the control-
ler. See Figure 5-l for parts identification. For operation
instructions refer to Section 2. The controller includes a
keyed connector for installing a remote switch and hour-
meter panel. This optional remote switch allows the oper-
ator to start and stop the generator set from another loca-
tion in the vehicle. The hourmeter records the hours of
generator set operation (Figure 5-2). The controller can be
removed by removing the two snap connectors and two
capscrews underneath the controller. This section covers
sequence of operation, and fuse, diode, and relay replace-
ment.
