[QUOTE="DaleH, post: 476980, member: 15636"] Small shorts in wires or carbon/corrosion build-up on electrical contacts can lead to similar 'on/off' striking and cause electrical humming or buzzing. Clean everything well or use NEW connectors. Also do a resistance check if you used old wires, as maybe one is corroded inside. Are the wires used too small? You need to measure the run BOTH ways and that total length is used to address the AWG needed for the amp draw. If the spotlight rating is in watts, divide it by 12.6 (nominal VDC) to get the amp draw. [color=#FFFFFF].[/color] [ATTACH type="full" alt="Wire Ampacity Chart.jpg"]106879._xfImport[/ATTACH] [/QUOTE]
