Hi all, I'm a new owner of a 2004 Sovran 4400.  It has the C-Charger Alternator Regulator which apparently regulates charging of house and start batteries from the alternator while the engines are turning.   One box regulates both the starboard and port alternators.  Starboard side regulation is working fine, no errors.  

Port side regulation is showing an error (Red light 1 second on and 1 second off).   The book says that error translates to "Can't turn field off".  

Anyone know what that really means?  And what to do to troubleshoot?   Is that error pointing me to a specific wire to check for continuity?  I read elsewhere that the guy who designed the system has left the company and they don't support they system.   

Thanks all for the help, Rich
