Connecting the Radar to Power Through the Voltage Converter
Connect the radar power cable (red and black) to the voltage converter output cable (red and black) using the supplied heat-shrink crimp
connectors. After crimping the connections, heat the connectors to shrink the housing for a water resistant fit.
nOTICe:
If you choose to cut the radar power cable, you must reconnect the in-line fuse holder.
Connect the radar to the water ground of the vessel using an 8 gauge copper cable (not included). Secure the ground wire to the radar housing
using one of the four mounting studs, an M10 nut, and flat washer.
