Fuel solenoids, how they work?

[Pavetim]

I have a 2001 Searay amberjack 290. There are 3 fuel solenoids and wonder how they worked. Are they normally off and when you have power they open or are they normally open and when something happens they close? My main question is about my generator one, It's not hooked to the control panel in the cabin but I started it yesterday and it ran for a little bit then died like it ran out of fuel, was wondering if the control panel when you set it to generator does that open the solenoid? Cause I didn't have it on generator yesterday

Need some more info on what you have. Maybe some pics

Normally fuel solenoids are ON only when something its feeding is running. If there is a selector switch then this may control it.

Yeah that's what I am trying to see. Even though the genny isn't hooked to the remote panel or the supply side maybe that switch still open the solenoid. I'll see what kind of pics I can get or maybe tomorrow I can get my multimeter and chk for voltage there.

Is this your FrankenGen? Still using the Westerbeke panel and the Onan?

It may be a wiring mismatch between the Onan and solenoid or some interrupted wiring from the Westerbeke panel when the Onan was installed. I remember it wasn't an easy task to get the Onan wired in to make juice.

They are normally closed, when you run power through them via the start/run circuit, they open.

This image shows the Parker Skinner VSC72120 fuel shutoff valves the factory installed on my 2000 380DA.

The valves have a two-position manually rotated selector knob.

When the arrow points to the left, the fuel valve operates under electrical control. The factory uses a tee wire harness to each engine, placing connectors between the fuel pump connectors and bringing that voltage to these shutoff valves, for this electrical control.

When the arrow points to the right, the fuel solenoid is always on.

Where is that selector valve, on the top? And Ga-boater yes its the "frankengen" I'm not even worried about getting it hooked up to the panel. From what I have read and from what you guy have helped me out with is all I need to do I hook up the hot, neutral and ground which will then supply power to the boat. The control panel is mainly for starting it from the cabin which I really don't care about, have no problem opening the engine bay to start it, have to open water valve anyways. I should have it hooked up this weekend for power but unless I need it for some reason I am not going to worry about the panel.

My Gen has a antisiphon valve in line so no need for electric valve. Just an option depending on how its laid out

Looking at the image, the valve shaft is extending towards the camera lens, between the inlet and outlet fuel ports.

The face of the valve shaft has a flat screwdriver slot.
