I'm running a MultiPlus 12\300\120-50 that is just installed. Default switch settings, connected to a bank of 2 8D 12v batterys. Mains on , the bulk and absorption lights have been blinking for days. Turned the Unit off, then back on. And in a few minutes I'm back to the same state. After a week of this I'm trying to figure out what is going on. One battery bad? Can' equalize? Is there a way to just turn off the charger without turning off the complete unit?
