POWER CONNECTIONS
The unit works from a twelve-volt battery system. For the best results,
attach the power cable directly to the battery. You can attach the power
cable to an accessory or power buss, however you may have problems
with electrical interference. Therefore, it’s safer to go ahead and attach the
power cable directly to the battery. If the cable is not long enough, splice
#18 gauge wire onto it. The power cable has two wires, red and black. Red
is the positive lead, black is negative or ground. Make certain to attach the
in-line fuse holder to the red lead
as close to the power source as possible.
For example, if you have to extend the power cable to the battery or power
buss, attach one end of the fuse holder directly to the battery or power buss.
This will protect both the unit and the power cable in the event of a short.
It uses a 3-amp fuse.
IMPORTANT!
Do not use this product without a 3-amp fuse wired into the power cable!
Failure to use a 3-amp fuse will void your warranty.
If you’re installing a speed/temperature sensor, read it's mounting instruc-
tions. Route the sensor’s cable to the power cable and plug it into the
connector marked “SPEED/TEMP CABLE”
After the cables have been routed, fill the hole with a good marine sealing
compound. Offset the bracket to cover the hole. Route the power cable
through the slot. Break out one of the holes in the back of the bracket for
the transducer cable.
