The C90 has three main battery switches , House on Off/Off ,Engine On
/Off, and Emergency Parallel. The Normal position is to leave both Engine
and House switches in the on position. The Emergency parallel is off.
Emergency parallel is rarely used as the boat has a Blue Seas Voltage Sensitive
relay (black box above switches that disconnects the house batteries from the
starter battery when the voltage on the start battery drops below 12.7 volts. As
soon as the charge system has brought the start battery back up to 12.7 volts it
reconnects the house battery bank and begins charging it automatically. The
batteries have three charge sources, First, 2 ProMariner Chargers (8 amp
engine, 20 amp house) that come on when shore power is connected and
breakers at dash are switched on. Second two 80 watt solar chargers (10
Amps) while anchored-automatic, third a 125 Amp engine driven alternator.
Thruster Battery Switches, These are
mounted above the main battery
switches and are normally on. These
must be switched off when swimmers
are in the water or for service. The
thrusters are very powerful and will
suck objects in the water toward them.
Do not operate for more that 30 seconds
at one time or motor may over heat.
