Posted: Tue May 23, 2023 4:09 am Post subject: Fuel Boost Pump ON Annunciator

Hello group,

I want to wire an LED annunciator light that illuminates when the fuel boost

pump switch is selected on.   I was planning on making this an "idiot"

light that just indicates the switch is on, not that the pump is actually 

working.   I can verify pump operation other ways.   

My plan is to wire the light directly from the boost pump switch.   Input side

of the switch will be feed from fuse panel.  Output side will have two wires, 

one to the boost pump and other to LED light.   

Seems simple but, as usual, I'm sure there may be other issues I'm missing.

Here's the annunciator I will be using.   https://www.steinair.com/product/green-led-indicator-light-12v/

I have also attached a diagram to show my plan.   Sorry it's an attachment.

I can't seem to convert the file to an attachable picture.

Thanks,

Shawn

    That would work just fine.

Hello

  add a T after the pump add a little pressure switch to it and connect your LED to the switch. If your pump is realy working your LED will come on.... otherwise ...?
