Major Components
There are three major components to the Start/Stop Controller, SSC. They are: the engine assembly, the control panel, also known as the local panel, and the controller assembly itself. Since the engine can be started with a remote computer, ithe control panel is also called the local panel.

High current wiring is contained within the engine assembly, with the exception of the alternator positive and negative wiring. Other wiring can be as small as #20 AWG, but the recommended size is #16 AWG.

TB1 thru TB4 are located on the controller assembly. There is a TB1-ENG, and a TB5 on the engine assembly. TB6 is on the local panel.

The engine can be controlled manually by switches should the need arrive. A diagram is included for the switch panel that is used to test engine assemblies at the factory.

Mounting the Controller Assembly
The Start/Stop Controller is protected against ambient humidity, but must be mounted in a dry location free of moisture, dust, and other environmental insults. The Start/Stop Controller will operate in temperatures to 70 $^\circ$ C (158 $^\circ$ F).

Wiring Diagram
The wiring diagrams show the only way to wire the Start/Stop Controller. Do not wire it in any other way, such as combining ground wires or battery positive wires. For safety purposes, always use fuses where shown.

Signal Names and Functions
Battery voltage set-points are specified for each voltage system, 12 or 24 volts, as 12 / 24 volts, respectively. Note that 24V units still require 12V to operate the starter and other engine controls. The SSC always operates from 12V.

TB1-ENG and TB1, Controller Assembly

These two terminal blocks are wired point to point. The signals on these terminal blocks are all low level and low current.
