You could connect your S terminal straight to the B+ terminal on the alternator. What that will do is sense a slightly higher voltage than if it was on the ignition switch and therefore slightly lower the regulated voltage output of the alternator. I would leave it where it was on the ignition switch for the 14.4 volts alternator output. Your boat could do with all the voltage for good operation of extra lights, navigation equipment etc, etc.. You don't want flat batteries out on the water do you ? Regards, Kevin.
