double solenoids

One of my coming challenges is to rewire the windlass....

I've already decided to run welding wire from the starter battery (via a switch) down the boat, rather than try and locate a battery and charging system at the bow...

But previously, i've noted that there is a strange combination of solenoids at the windlass, that I didn't understand...

A bit of research, and i've got it sorted!

Application of a low power 12v supply to the energising side of the solenoid via a switch and it switches the -ve power feed over to a +ve... ie provides power to the windlass.... if the switch is 2 way, or 'up' and 'down', then it energises either one solenoid or the other ie reverses the power supply to the windlass...

A simple solution to the problem, and a lot cheaper than a single reversing solenoid.

I also need to add a breaker, as there currently isn't one.... only, not sure what rating I need.... I don't actually know what power the windlass motor is....

I think its a Simpson Lawrence Seawolf 520, but googling doesn't seem to help give me an answer... and i'm not 100% sure that i've got the right model either until I physically check!

  1. Neil, I have a Jeanneau supplied ETA freebie which was given when my windlass would not work. It is now surplus to requirement, and unused. I think around £80, yours if you want it.
