Wiring to the searchlight

Figure 5

The RCL-300A searchlight is supplied with a 15-foot integral wire harness. If you must lengthen the wire harness, use heavy duty wire to minimize the voltage drop. This is especially important for the WHITE 12 AWG lamp power, BLACK 12 AWG lamp ground, ORANGE power wire and BLUE ground wires.

Following the wiring scheme above and Appendix C. use the supplied butt connectors to connect the Master Controller to the searchlight.

Wiring the Point Pad™

The RG-59 coax cable is supplied without the “F” connectors attached for ease of routing. After the Coax cable has been routed, strip the insulation and crimp the “F” connectors in place. Screw the “F” connectors to the Master Controller and the Point Pad™.

Wiring to the power supply

The power source must be a fused 12 VDC, 30-amp supply or a 24 VDC, 15-

amp supply. Following the wiring scheme in Table 1, use the supplied butt connectors to connect the Master Controller to the power source. Refer to Table 2 for proper wire size for connection of the input power lines.

NOTE: As per the wiring scheme, the ORANGE wire is connected to the positive terminal and the BLUE wire is connected to the negative terminal of the power source.

CAUTION: HID light systems, when first turned on, have a high inrush current requirement of 25 amps. If you activate the light and the lamps flicker on and off repeatedly, check the voltage being supplied. This condition can be experienced with voltage input of less than 11.5V.

Functions of the URC-300

The URC-300 Master Controller is designed to perform up to six different duties on searchlights, winches and other electrical devices. The Master Controller provides optimum voltage to ensure brightest performance and long lamp life, regardless of boat system voltage fluctuations. The Master Controller is compatible with devices requiring 12 VDC through 24 VDC operation.
