First time out since launch the starboard alternator was over charging @ 16+ volts. Returned to the dock checked all connections were tight, gauge was accurate. Restarted it several times, same problem. On the fourth start the charging rate was correct and for a couple more starts. I have a Charles in line digital charger. The batteries were fully charged (12.45 volts) when this happened. The charge rate was correct at idle but jumped to 16+ at 1,000 rpm.
Engines are 2001 8.1 liter with 500 hours and 100 amp alternators.
What could cause this, I don't want to replace the alternator at $800 nor do I want it to happen at an inopportune time.
