| Post subject: | Bilge pump wiring |
I want to add a second bilge pump. I have a high water alarm which I would like to use just the wiring for power supply. They will still be separate systems. I know I can't just put a quick connect on it, I mean I can temporary but I am sure it will corrode after just a few weeks. Do I need to cut the existing wire and Y connect the two using heat shrink wire covers? Whats the best way to wire this? |

Personlly, I would leave the high water alarm alone. You must (on a boat that size) have a 2nd battery that is NOT powering the stock bilge pump. Connect your 2nd pump (with a float switch) to that battery. In other words, 2 pumps powered by 2 differnent batteries. If one battery is dead, at lest the other pump will work. |

As standard, by 2009 278 boat had 2 bilge pumps, engine and forward bilge. ( and a high water level alarm in the engine bilge). Both pumps were supplied from the one systems battery ( now, from the two 110AH systems batteries). The +12V supply breakers for them are piggy tailed. |

Thanks, That is great info on what was wired standard. My 258 does not have a forward bilge(bad bad Four Winns) so I want a secondary. I will check what the fuse/breaker is on the high water alarm and probably pig tail off that. A high water alarm should not draw hardly any power, its just a float with a buzzer. Any recommendations on an auto bilge pump? Rule seems to be the most common and so far I haven't had any problems with them. I am thinking around 2000 gph if the hose size works with the thru hull I am considering using. I haven't check the size of it yet. |
