Batteries not charging from any source
Hey everyone, I am a technician buy trade , and I understand that my batteries on my 2003 hurricane 33sl charge from land power , generator, and / or the alternator. When plugged to land my converter has 13.7 volts , the same when I run generator , but my batteries stay at 12.5 volts. When I start the engine , my chassis battery does not get a charge from the alternator ,neither does the coach batteries. I checked the alternator and it is putting out 14.5 volts. What am I missing that is causing none of my batteries to receive a charge . I'm a new owner and know nothing about an RV as far as how the system is set up. Thanks for any help.
