I am attempting to replace an bilge pump with float switch with a new Rule bildge pump with built-in float switch. The original bildge and float has the following - black wire and brown wire to pump and two brown wires to float. The new bilge pump has one black wire, one brown wire and one brown wire with white stripe. The brown and white stripped wire is marked manual. Easy enough to wire the black to black and brown/white to original brown wire off pump, which allows the manual switch at the helm to manually turn on the bilge - works perfect. Now for my issue. I have attached the remaining two brown wires in every configuration and I am not able to get the automatic to turn on (I am able to get the automatic to work when I have the switch at the helm turned on and the manual brown/white wire disconnected - so I know the built-in float switch works) Any ideas on how to I get the float switch to work and still let me have the manual connected?
