And it should also have an in-line fuse in the wiring.
Jon,
It is both. Depending on the pump you have, many come with both a brown and a brown with white stripe. I guess those may be the ones with internal float switches which is the case with mine. Either way, power to the float switch comes directly from the battery. On our 34s you would see (if its still there) a brown wire that connects to the common terminal on the back side of the battery selector switch from the engine compartment side. Lift the float switch and the pump comes on even if the battery switch is off. The second wire from the pump or a wire on the other side of the separate float switch (not the same as the one directly to the battery) goes to your DC panel. If you look, and it hasn't been changed, there is a switch (third one up on the left)labeled bilge pump. There is also a fuse (bottom on the right side of the 12 volt portion) labeled automatic bilge pump. The second wire goes to that fuse. Flip the switch and the pump runs even if the float is down. That second wire is back fed with 12v even if the float activates the pump and the manual switch is off allowing the light to come on, so you know what that noise is. Nice.
That was the professional foot model while I stood on the settee to take the picture.
Good idea Allan. Our 34s already have a 2nd pump, i.e. the shower sump pump. While smaller than the main pump it still could serve as a 2nd pump. On my boat it is wired into the fresh water pump electrical breaker. Don't know if it's OEM or PO installation. Never ever having heard it unless using the shower, I only realized it I thought the pump was burned out and bought another one to replace it, only to find out the new one didn't work either
! Turning on the fresh water pump brings power to the float switch in the shower sump and pump works when water level in the sump is high enough . I have been thinking about wiring this pump to the second battery so it becomes useful as a 2nd pump as well besides working for the shower. The sump is built however to avoid draining into the bilge and I do not want to change that so I question the usefulness of this plan. Any ideas without stealing this thread ???
With apologies to Jon (but related), Claude, with the rather large capacity house bank anyway, I almost wonder if by the time we need a second pump, we are in a lot of trouble anyway. The second pump would only have the start battery capacity to do its thing in an emergency situation. Considering that my boat is plugged into shore power about 99 44/100% of the time (it seems) I wouldn't deplete capacity anytime soon. Hopefully, someone would see the continuous stream of water and do something. If we are out on the water, I don't think we can get enough pumps or batteries to keep us afloat without somehow finding the source of water and stopping it.Good idea Allan.
