Notes for both FUEL 3100 and DIESEL 3200:
Use a Navman junction box or any simple wire
to wire connector system to wire the power/data
cable. Tape or cover any unused wires or
connectors to protect them from water and keep
them from shorting together. The unit requires
between 9 and 30 V DC power. To allow the
engine hours counter to function properly the
unit should be powered only when the engine's
igniton switch is turned on. With twin engines
the unit ideally needs to work when either one
or both engines are running. If acceptable power

is available wire the unit through each ignition
system seperately using an On/On switch.
Alternatively wire it through a seperate switch to
the vessels 12 V power supply. The units must
not be powered from both ignition systems
simultaneously.
If a Navman connector box is not used a 1 A fuse
must be fitted in the power supply (+ ) line.
The instrument's alarm output is switched to
ground to sound the alarm, 30 V DC and 250 mA
maximum. If the external alarms require more
than 250 mA DC total, fit a relay.
