When charging a 100Amp battery, the output wires (+ and -) are HEATED and changed to a larger value. The fan turns on after a strong heating of the power transistors (they may burn out). I installed a 12 volt power supply (from the charger / telephone) for constant cooling and the fan is more powerful. Everything is working.
