I checked the breaker and its on. All of my pumps quit. If i try to turn them on manually i get an error code both forward and aft bildge pump. Soon as i turn the switches back to auto i can clear the alarm and it says all systems normal. But pumps are not working. Any ideas where to look next?
 
Not likely that they both went out at the sames time. You're going to have to get down in there and see if you actually 12V to them... sounds like not. Could be corroded connections.
 
Yeah, it's going to be a trip to the bilge with a meter. Maybe start at the float switch, and keep working your way back until you get to the switch. Somewhere in that path is the problem, and you'll see you don't have 12VDC. I think both failing, as Jim said, is strange, unless there's a common ground or something being used for both of them? They should be wired to the batteries, so even with the battery switch off, lifting the float switch would normally engage them.
I'm not sure what error code you're talking about, but I don't have the same system on my boat. I know there is a high water bilge pump alarm on my boat when that pump gets triggered by that float.
 
Thats a normal message for the Searay Systems Monitor. Are you sure they are not working or is it that you don't hear them? They are quiet pumps when not pushing water. Do you have water in there or is the bilge dry? Check voltage on the wires with a meter to know for sure.
