September 4, 201114 yr 13.8 is typical for economy use.Voltage being higher after load, sounds like computer controlled regulator.From what i understand, there is no way around it in terms of keeping voltage high all the time even when there is no load.
September 5, 201114 yr no no no.. I'm trying to help you sync your voltage up from front to back as you have stated is not in sync.When you have a load, you will have higher voltage(then will be compensated at the same time and drop due to current demand)Your vehicle isn't "stupid", you are just wanting a higher voltage when there is no high load and it's not necessary all the time...HOWEVER, this could lead to not keeping the batts maintained...And since you have stated just 2 D3100s drop below 12v, i believe it's already happening!So, you need something to force the vehicle to charge higher.You need to be charging between 14.4-14.9v in the back!So, you will need these cable runs REGARDLESS!Then, contact DC Power or Mechman for a voltage increase solution.
