John T Question about charging a second battery. I have a cargo trailer that I use to go to bike rallies and other things. It has brakes and lights in so I have a 12 volt battery. I don't have a diode in the charging system I just unplug the trailer when I park to keep from disgharging the truck battery. I checked the charging voltage, with the truck running the truck battery was 14 volt and the trailer battery was 12 volts. I then used another battery with jumper cables to another vehicle and had the same result. I asked a friend of mine who is an electrical engineer at NASA and he couldn't explain it. Do you have any thought about this? The trailer battery charges and I have no problems. I am just curious I would think that the voltage would be 14 volts unless the truck battery draws the voltage down. Bill
