my victron centaur 12/30 is dead. no green led and charger output ranges from mv up to 2v depending on the battery type. voltage gradually increases from mv to 2v. I have got dc 200v coming out of the rectifier and no shorted transistors also have check the temp sensors, and fuses and checked the yellow transformer has resistance and no shorts... any ideas on what i should check next? thank you. cheers, Aran.
