My Statpower charger turns a fan on and off, often in response to me turning on a light. Why does it happen?
The fan is used to cool the electronics when higher currents pass through the charger. Fan turn on/off is determined by many factors including the ambient air temp. In general the fan will come on for less time and less frequently when it is cool than when it is hot inside the compartment where the charger is located. When you turn on a light it draws more current from the TrueCharge. Sometimes this additional draw is enough to cause the fan to come on. Likewise, when you turn off the light it reduces current so that the fan is no longer needed. Q: My TrueCharge works fine when connected to shore power, but stops charging when using the genset. The lights on the status panel blink. A: Your Onan genset has a small 2 amp charger that feeds through a voltage regulator to the house battery. Remove the wires from the regulator. There should be two terminals – one with a single wire and one with two wires. Remove the single wire and tape the connector at the end of the wire to guard against
