I had an interesting problem this week. Had a 50 ft motor yacht throw a large wake inside Obstruction Pass and got caught w/stern into the wake and took water into the motor well, which ended up in the bilge due to bad bad seal on a new access cover. ( I spent yesterday resealing it). The PROBLEM: when the float switch activated the bilge pump, it did not work, or at least not well, the switch and indicator ligh on the dask showed power as well as the two accesory switches next to it and the fuel guage pegged to "0-".
I recently has a new 225 Honda installed and figured they had messed up the wiring when redoing the guages,"WRONG" assumption. So, I took it back to the dealer and after some trouble shooting, the tech was a little stumped, then went in a made a phone call to someone, then came back and started cutting wires on the "RULE 1500 GPH Pump". That made the other lights go out and the fuel guage go back to normal operation. The guy whome he called told him the Rule pump has an internal short and was "BACK FEEDING" the electrical system. Not being an electrician, seemed plausable. The short and long of the fix was a new bilge pump which solved the problem.
I am posting this just for information in caase someone elses runs into this type of situation. It only cost me an hours labor to find and fix the problem, so I don't feel bad about that.

Good Info!
How will I ever retrieve that from the memory banks when I need it?

If the electric pump had a short, it should have blown the fuse in the branch circuit which supplies power to the pump. If the battery supply to the pump was not fused, that is an error in the installation.

There is a breaker right under the switch but didn't pop it, must have just been a trickle on the back feed.

A trickle wouldn't have caused that.

This smells like the "trailer lights with a bad ground" bug
that turns up over and over.

I've been out 3 times since the change and everything is still normal. Probably go again on Saturday. Maybe when I was down I will flood the deck and let water get do below deck by pulling the plug from the bait tank and see if it works w/o a problem.
