Bilge Pump Problem

I have a 2008 Montauk 190. All of a sudden the bilge pump stopped working. I checked the circuit breaker in the console and it was alright. What I do notice is that the bilge rocker switch does not light up like it used to. Could the switch be the culprit? Thanks--Fred

That's where I'd start.

Simple DC circuit debug job.
Get a meter. First determine if power is getting TO the
If the power wire is not hot, trace it back.

Here's a wiring diagram for your boat.

Ok. The bilge pump was frozen as a small pebble was found. I removed it and it came back to life. However the pump will not shut down. The rocker switch light comes on faintly in the off position. It comes on stronger (normal) on the run position. I played with the intergrated float switch on the pump but nothing happened.
The other thing is when I disconnected both wires from the rocker switch the pump still ran (although it did not light up. Any ideas before I go out and buy a new bilge pump. (I bought the breaker switch which I thought was bad till I found the impeller stuck)
Any help is appreciated.

Looking at the diagram looks like power will go to the pump through the float switch even with the switch wires disconnected or the switch in the off position. It appears to be powered through a 5 amp breaker in the main breaker box.
Float switch may be stuck in the on position.

9, well it won't shut off. I tried playing with the float switch nothing. The rocker switch is lighting correctly when turned on the light goes on but the pump keeps running regardless if the switch is on or off.
I now it's probably something stupid but I can't hit on it. I called my mechanic to ck it out during the week. I cancelled my outing with the new motor, jeez did that feel bad.
Anyway thks for the info, I might putter with it again tomorrow as I was to tired to keep working on it.

Fred, on page 2, item 17 shows the Attwood Sahara S1100 pump.
The pumps have a 3 year Warranty. If it won't shut off has to be a bad float switch in the pump assembly unless it was mis-wired somehow. How about the test knob referred to in the installation? Good luck.

Problem resolved. Brought in a Tech and he fixed it in 5 minutes. Don't ask me what was wrong I don't even know..

The [sump pump] is the most regularly replaced part of my boat. Yes sometimes it has something to do with all of those electrical loops that Tribolet seems so familiar with but most of the time it is mechanical-- the float is gummed up-- or the wires in the bilge have been infiltrated with water.
Tough how these bilge [conditions] even affect people with big new engines :).
