nchooks Posted October 15, 2014 Share Posted October 15, 2014 Hello, my first post here I hope you guys can help. I recently installed a Surepower 24023A battery isolator in my new 2015 F250, 6.2 gas engine. The isolator is for my auxillary battery bank of 2 deep cycle group 27 batteries for my slide in camper. The alternator and isolator require a 12 volt feed from an ignition circuit to excite the alternator/voltage regulator to "tell" the alternator to turn on. I found a bundle of blunt cut wires uder the drivers side dash and one was labeled "Run Acc". I checked that wire and it supplies 12volts when the engine is running. I used that wire to hook up the exciter terminal on the isolator. Everything checks out, I have voltage from the alternator and to the starting battery and to the auxillary bank. The problem I discovered is when I remote start the engine(Ford factory installed) that circuit I used is not energized and the alternator is not turning on. Put the key in the ignition and turn it to run and every thing functions as intended. Does anyone know where I can find a circuit to use that will be energized with both standard start and remote start? Thanks for your help.
