DO NOT operate boat with batteries in
“COMBINE BATTERIES” once the engines are
started or serious engine electrical damage
may result.
!
WARNING
Use the “COMBINE BATTERIES” position only if
all batteries are near the same voltage. If one
battery is strong and the others weak, high
current could cause battery damage.
!
WARNING
The battery switch has three (3) settings:
•
“OFF” - you will
have no power to
the engines.
• “ON” - you will have
power from both
batteries.

Digital Voltage Sensing Relay (DVSR)
The electrical system on your boat includes a
digital voltage sensing relay (DVSR) located on
the battery switch panel (See fig. 4.1.2). The DVSR
allows charging of two independent battery banks
from a single charging source. When the voltage on
the start battery rises to a charged level, the DVSR
engages allowing the second battery to charge.
When charging stops and voltage falls, the DVSR
will disengage, isolating the two batteries from each
other. Dual sensing functionality enables the sensing
of two battery banks, allowing two way charging.
Even with the battery switch turned “OFF” The
bilge pump will remain operational with power
from the starboard battery.
Clean power for the DTS system will still
draws power from both the port and starboard
batteries.
