I Launched the boat on Monday after winter storage. Both engines started but had an message for low voltage on the starboard side. Before I stored the boat for the winter, i got the same message for the port engine. I though this was related to leaving the boat as it was on land and batteries were discharged. Before launch, I charged the batteries, launched with no issues (starboard started after a the second try and port after from the first try). We went out yesterday, all good, had the low voltage but then went away. got up to cruising speed for a about a minute and all good. After a about 15 minutes, I was idle and noticed that the starboard engine with 0 rpm. Low voltage message. I tried to restart but restart was aborted, "Critical - Start Sequence Aborted". I tried to key engine off and restart and nothing. I started heading back to dock with port engine. I wanted to give another try and the starboard engine started. we docked at a gas dock and I checked all battery connections. it started again and then when idle it shut down and would not start again. Voltage on the starboard was around 11, it went down as low as 8 - 9 and when it was running it was around 13 - 14.2. I measured each battery and it was 12.7 V. What is going on here and did I blow my alternator?
Any help to troubleshoot appreciated.
