I'm using a 12/12-30a isolated charger that gets very hot. I want to fit a cooling fan to help keep the temperature down a bit. I am using the engine is running function to turn it on. I have no way of getting an ignition feed to it, that I could also use to power the fan.
My question is. Is there any way that I could use the L/H pins to power a relay to enable me to use power from my battery bank when the Orion is operating to power the fan?
