2010 242 Bilge Pump Wiring

[Randy2010242]

Hi!

I need help. I purchased an Atwood Tsunami to replace my factory installed system.

I thought after I got the old out the battle was won.

I was wrong.

The new pump has 3 wires - black, brown, and brown and white stripe.

My old system had two grey wires from the harness going to a float and a brown and black wire going to the pump.

I have a toggle button and an indicator light on the dash.

Previously when the float kicked the pump on I received and indicator light adjacent to the button and I could manually turn the pump on with the button which also turned the light on.

I can’t find the wiring combination to restore this functionality.

Please help!

Perhaps this schematic of the bilge pump and float switch on my 2007 240 will be useful?

Thanks -

Yes that is helpful and I suspect mine is wired the same. Based on this schematic and the fact the new bilge has an internal float switch, I don’t thing there is a way to illuminate my helm light when the bilge automatically comes in as I don’t have a stand alone float switch any longer.

Thanks again!
