b. A proper ground connection is critically important for corrosion protection and helps to ensure the ignition protection of the unit by ensuring it does not carry any stray current.
c. NOTE: the ground is not referring specifically to a bonding system but for outboard boats generally refers to the outboard engine negative terminal, or its bus, to the DC grounding bus. This connection shall be used only as a means of maintaining the negative side of the circuit at ground potential and is not to carry current under normal operating conditions. See Figure 19.
