Would a relay to bilge pump make sense

[mike_israel]

Hi All,

The one fuse that will occasionally blow on Amphi is to the original style bilge pump.

It recently occurred to me that when you upgrade things like headlights on many older vehicles, it is often common practice to wire the switch control to a dedicated relay which is then wired between the battery-ground and lights.

It seems like this sort of arrangement would make sense for Amphi. Wire the bilge switch to a relay and then the pump directly to relay and battery with a dedicated in-line fuse. This way the pump could bypass the fuse box and use a heavier gauge of wire.

Has anyone done this? Does it make sense? I know just enough about electrical systems to be dangerous so if someone can diagram whatsuch an arrangement should look like, that would be great.

Cheers.

Mike

Yes that's the way I do it,so the switch doesn't have to carry he load of
the current. You use the switch to control the relay.
