Have the Victron 3000 12v and a phoenix multi control which the previous owner says was a remote for switching the charger. When using the microwave or coffee pot at the dock with power, noticed the blue light flashes on the multicontroller and the yellow light signaling the bulk or absorption or float goes off. Is there a manual that describes what these lights mean. I do see he had set the dial to 16. so when the blue light is blinking, does it mean the charger is not getting the amps it needs to charge?
