I've searched the forums for the last hour and have still not found the answers to how to make my own back-up battery connection for my GRT's. I am using the third power input for this function and have found a 5.8 AH gel battery that will power the essential GRT units for about an hour if all else fails. Also want to use this back-up to power the units during engine start per the GRT installation guide.
So, I need to be educated on how to charge this small battery when not in use and anything else I am not thinking about. Anybody?
