Wiring Connection
Keep electrical and transducer cables
away from alternator or other noise
generating electrical cables. Avoid
connecting the instrument to power
circuits that share loads with ignition,
alternators, inverters and radio
transmitters. Electrical power supply
connections should always be as short
as possible.
Connect the red wire from the gauge to
the positive supply through a 1 amp fuse
or a 1 amp circuit breaker . Connect the
green wire from the gauge to the
electrical ground.
Connect the fuel
transducer to the
gauge as follows:

fuel line. The transducer MUS T be
installed AFTER the main fuel
. It should
be located well away from any area where it
will be effected by excessive heat or vibration
from the engine. It is preferable to mount the
transducer in a vertical position.
Drain all the fuel from the
fuel line. Cut
the fuel line and using the fuel hose attaching
clips provided install the transducer so that the
FUEL IN side of the transducer connects to the
fuel tank.
