what drained my battery

[jasguild]

I accidentally left on my main switch and noticed that my battery was completely dead in about a week time. i am just curious what electrical device could have drained my battery. All switches and radio was off. The only thing I could think of was my bilge but I believe the bilge is wired to work wither my main switch is on or off.

Any thoughts?

1) Radio
2) Auto Bilge pump
3) ECU on the engine
4) Throttle Guardian
5) possibly a weak regulator draining back


It's normal on these boats. That's why they put a switch on it.
