Default Code Help

My wife has a 2011 Softail Deluxe. Sunday we went on a short ride and she said her battery light came on. It stayed on for a couple of miles until we stopped for coffee. We then road a few more miles to my class and the light stayed off. About 30 minutes later she left and said the battery light came back on a few miles from class and stayed on until she got home. She tried to start the bike an hour later and it would slowly turn over but not enough juice to start so they pushed it into the garage and she hooked up the battery tender. When I got home I hooked up the FP3 tuner and read the codes. they are as follows.

P0562 - ECM voltage low
B2119 - Fuel pump output overloaded
B2121 - Starter output open
B2272 - BCM or speedometer voltage high

Other than the battery light, the bike seemed to be running fine.

Any ideas what could be causing this?

Most likely a bad voltage regulator or a bad/loose connection in the charging circuit.

Had something similar happen when I had a loose ground wire at the regulator
