Dan, yes, what you describe is exactly how it would work. There is a 0.2mA continuous current draw from the AUX 'input' which is partly just the current draw for the sensing potential divider circuit on the board. That 0.2mA should not cause an issue with battery charge balance given there may be that much leakage just from battery posts and dirty battery case conduction paths... cheers, george.
Thanks for the great information on this George. I like the looks of this and am wondering what the OP asked as well if this will fit in an 80 factory knockout spot? If it does I will your little diode removal and it will be just what I'm looking for.
