cranking circuit on which ever battery you have selected or both batteries. With this
system you are required to manage the battery system, keeping both batteries charged and
never run the second battery dead. Sitting listening to an amplified stereo system with the
selector switch on “all” with lights on can drain both batteries. The best feature of this
switch is you can disconnect the electrical system of the boat and engine, and the
amperage draw for the computers and stereo memory during long and short term storage
will be minimal. To maintain optimum performance, make sure to manage the batteries
properly.
#3 The Voltage Sensitive Relay (VSR):
The voltage sensitive relay is basically a switch that connects the cranking circuit battery
to the house circuit battery, once the starter battery is fully charged. This allows the house
circuit to be separate from the cranking circuit completely. This is a true isolated, separate
set of circuits; house and cranking with two separate batteries. The common ground
connection and this VSR switch are the only way these two separate circuits can connect.
The switch is normally open, but once the engine is running and the voltage comes up on
the starting battery and it is fully charged, the VSR switch closes, allowing charge current
to flow into the house battery. This allows the alternator to supply current to charge the
house battery and supply operational current to house loads.
Once you shut down and the alternator is no longer charging, the VSR switch will open,
separating the two circuits again. Again the VSR has allowed two circuits to be separate,
so now any power you draw with the engine off; will come from the house battery. You
can listen to the stereo until the house battery is dead, but you can have the peace of mind
knowing that all you have to do is turn the key and your boat will start. No fumbling with
any switches, it’s all automatic.
Now that we have separated the house and cranking circuits, we can use batteries
designed for specific uses. You always need a cranking battery for the cranking circuit,
but now you can use a deep cycle battery on the house circuit. Deep cycle batteries will
handle the load and discharge cycles much better then cranking batteries on the house
circuit. A group 24 high-ampere hour deep cycle battery is recommended for the isolated
house circuit.
If you have a large stereo system and you spend a lot of time listing to it with the engine
off, upgrading the house battery system to two battery’s will extend the amount of time
you can listen to the system before the batteries are dead and require charging. Using two
deep cycle batteries in parallel on the house circuit will dramatically increase the amount
of time you can listen to high end stereo systems. Contact our dealer for a battery system
upgrade.
The cranking battery is the primary battery that is only used to start and operate the
engine. Having the cranking circuit truly isolated from the house circuit is the ultimate
upgrade; it prevents cranking voltage spikes from causing any problems with the onboard
computer network. With the VSR equipped systems, you will notice that when you turn
on the key, the stereo will come to life as will the dash instrumentation, yet when you
crank the engine over to start, they never blink. The stereo never skips a beat and the
instrumentation stays powered.
