This is what I sent to Ford. Perhaps some other people on this forum should ask Ford wtf goes on.
Thank you for getting back to me about this issue. One problem with the explanation is that I have 14.13 V coming out of the power in the 7 pin output. Wherever you got the information about my question is not accurate. I can't see how 10 V should come out of the alternator. There are a lot of people in the RV community that need a straight answer to how the control module in a Ford camper package supplies power to the campers connected by a 7 pin connection. Many camper power afficianado's install smart camper battery chargers to their alternators which combine a solar power system and the output of the alternator, or run a direct line from the truck battery to the camper battery. In a recent camper forum, there are over 60 replies to my original post about asking what is going on in charging systems.
What I would like to know from Ford is what the voltage and amp values should be coming out of the 7 pin 12V to the camper battery....1. when the camper battery is just being maintained, when it has a full charge 2. when the battery is 20% depleted, what should be going to the camper battery 3. If the battery is 50% or more discharged, what is going to the camper battery from the 7 pin connection.
What does the control module installed in a Ford Super Duty actually camper package do? There should be a definitive answer or general explanation of the parameters of the electrical power going into the camper battery from the control module.
Could someone please forward this to an electrical engineer at Ford. I appreciate the communication from Ford CRC, but feel that there needs to be better communication and explanations to the customers who purchase a Super Duty with a camper package.
