Do I need an auto bilge?

[wakina]

Please compare switch types, a float switch will have a tendency to stick over time from the crud that some how always seems to find its way into the bilge resulting in a dead battery as they always seem to stick in the run position. There are sensor switches with no moving parts to stick that will only power up the pump when it senses water and will not power up with petroleum products (gas or oil). There is a simple test to determine if the switch will power a light on the dash with the power out wire on the switch. But I don't think the bilge switch and pump circuit has a relay in it as most pumps use so little power that there is no need for it. Note~~ If you decide to add the light if not already there then you would also have to ground the newly installed light, should be plenty of places in the dash to do that.

The whole installation sounds a lot worse than it really is. The hardest part is most often bilge access to perform any work that you might want to do.
