I have looked at circuites that I thaught would do the job.
The circuit is current flow or Voltage.
I am trying to make a electronic switch that will switch from a 12V main battery when it is charged in my car to a nother battery that needs charging.
The problem I have is when the car is running the battery is being charged at 14V DC and this indicates to the circuit that the battery is charged but it is not.
How do I get around this problem.
