I have a 2018 Jeanneau SO419. With the boat came a Quick bow thruster and Quick windlass. I have had the boat three seasons going into my fourth. Everything on the boat worked fine last year except the house batteries were not holding a charge and I wanted to increase my house bank. So I changed all the batteries...for the windlass and bow thruster I replaced the two Intimidator 55ah batteries to two Mastervolt 55ah batteries and reconnected everything the same (i.e., wired in parallel)...the bow thruster does not work unless I depress the Soderep ecans switch under the V-berth, which I never had to do before, there is a button switch at the helm. I haven't tried the windlass but I its all wired off the same batteries and switch so I am not sure where to go from here? How do I test the Soderp ecans switch or do I just replace?
