Possible Charging Issue? Pulse coil?

[CatCam]

Update: I replaced a battery and changed the rectifier/regulator.I cleared the old codes and she is now putting out a solid 14.35v while running and a pleasant 12.9 with key on engine off. I have not had it in the water yet this season but is great on muffs. Just thought I'd give an update for anyone coming across this in the future. Thanks for everyone's help.

Those seem like good numbers -- My F90, while running is 14.5 - 14.8......not running key on at 12.9.....seems like you cured the problem!! == with a little forum guidance!
