I got new batteries a year ago for our 1991 Hunter 28. I usually do not plug in the charger, but I do leave the battery switch on "number 1" along with the DC Main and bilge pump switches (just in case there is a leak). I usually start the engine every couple of weeks if we are not using the boat. I have twice found that the number 1 battery has been discharged. I do not believe that the switches draw that much current to discharge a new battery--even in winter; but I may be wrong. The bilges are dry, so I know the pump is not activating. What do the E.T.'s have to say? Gary s/v "serenisea"

If it is wired correctly.......
Gary: If the boat was wired correctly, you should not need to leave the batteries switch on. They should be wire so that (even in the OFF position) you bilge pump would work (if the float switch trips). Have you ever test the float switch (with the batteries off) to see if it works? Maybe you need to test the draw on the battery to see if there is SOMETHING that is draining the battery down.

If the battery switch is on...
...make sure there is nothing else left on. Check your VHF to ensure that it is off.

Bilge Pump
I also have a 1991 H28 with everything off the bilge pump works with the float arm up. Ron
