Soderep ecans switch for bow thruster and windlass

[joedunn]

I have a 2018 SO419.  I am having trouble with turning the bow thruster on via the Quick switch at the helm.  I have power to the helm switch. I replaced the two Intimidator AGM 55AH with two new Mastervolt 55AH batteries wired in parallel (as before) that provide the power to both the bow thruster and windlass.  The battery wiring appears correct since there is a photo in the owners manual.  All the fuses in the circuit appear good.  The bow thruster will turn on via the helm switch when I depress the Soderp ecans switch located in the V-berth which I have not had to do in the past three years I have owned the boat.  Further, the Soderp ecans switch does not stay on, after a certain period of time it closes the circuit.  Is there a way to keep the Soderep ecans switch on?
