Super User Way2slow Posted May 19, 2014 Super User Posted May 19, 2014 Are they coming from a motor or small sensor? Quote
Super User WIGuide Posted May 19, 2014 Super User Posted May 19, 2014 You might want to try looking on their website for a manual to be sure. Quote
sparky241 Posted May 19, 2014 Posted May 19, 2014 Black and white indicates 110v, is there a green anywhere near it for ground,can u post a schematic Quote
Super User Way2slow Posted May 21, 2014 Super User Posted May 21, 2014 It's very common to see black and white used for 12VDC with boats. There are no sensors in the motor so that's probably the power for it. Not saying the motor is good and going to run if you connect it. As for a particular polarity, it does not matter, the motor is just going to run in the direction the wires are connect and the switch reverses them for which direction it needs to run. Quote
