A cmp012202000 is connected to 100Ah LifePo4 battery.
Setting the Multiplus to charge turns on the right blue LED (mains on) and the yellow LED ( bulk) on the attached multi control panel. After 10 seconds or so, the fan comes on, and another few seconds later, you hear a lot click, the LEDs go off (the digital display of charging AMPs set to 8 atm stays on).
Sometimes, when the yellow absorption LED is on, the charger operates continously.
Also, if I change to On (instead of Charge), it will turn off as well. First both blue LEDs are on, than all are off.
I am desperate, sitting here on a campground with the need of a working setup.
