Power connections for TriFinder 2.
If possible, keep the power cable away from other boat wiring, espe-
cially the engine's wires. This will provide the best isolation from elec-
trical noise. 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 sure 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.
CAUTION:
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 war-
ranty.
This unit has reverse polarity protection. No damage will occur if the
power wires are reversed. However, the unit will not work until the
wires are attached correctly.
