Vessel: 1997 330DA Issue/question: How exactly is this switch suppose to work? Currently, the switch on the right "control/up and down" works. It operates the windlass without hesitation. The "main" switch currently does not light up at all in either position and my bow (foot) controls are not responding. According to FP Marine this switch is a VLD1-3 Carling (ON)/OFF/(ON) double pole momentary rocker switch, independent clear lamp in position #1. SR part # 1733928, 681494 VLD1-3 I don't understand why is is a momentary on switch. Hopefully someone can explain this to me. Seems like you would want this to be a simple ON/OFF switch.
