 ELECTRIC PROTECTIVE SYSTEM
SYSTEMS OPERATION
INDIVIDUAL CIRCUIT DESCRIPTION
The information that follows show the current flow through the wiring schematic. As switches are
opened or closed, either automatically or manually, the current flow of the individual circuit affected is
shown schematically.
Also included (on each facing page) is a story that explains all the components involved for this
particular condition, and why the current will take the path shown.
ENGINE STOPPED (Fig. 1)
With the engine stopped, power is always available across terminals 3 and 4 of time delay relays
(TD1 and TD2) and across terminals 5 and 6 of electronic speed switch (ESS). At this time all switches
are in their normally open or normally closed positions.
