I have a 2005 Rinker 300 Fiesta Vee with twin 5.0 liter Volva Pentas with 120 hours on them. This issue just started this year. My port motor will die off while under way. When I go to start it, the battery clicks as if it is a dead battery. I put the battery switch over to bypass and the engines starts and remains running. My both alternators are putting out 14.5 volts and when I check my batteries they read at 13.5 volts. I just installed a new house battery and a new starboard battery. With everything shut down on the boat and it hooked up to shore power, my voltage at my panel only reads 11.5 volts. I have also repalced the battery isolator. Need help

My guess is a loose or corroded cable connector, or a failed alternator.
