To prevent the Optimus EPS/360 system from draining batteries while
trolling on a single motor, it is necessary to connect the batteries in
such a way that the PCM is always connected to a battery being charged.
Figure 4-15 illustrates a possible triple engine connection using
battery switches with a combine function and an automatic charging
relay (ACR). In this example, if the user is trolling on the center engine
the ACR will detect that the starboard battery is being discharged
and connect it to the center battery. This ensures that the steering
system will not deplete the battery.
