Have 923 with the four battery setup 2 which are original and two that I put in myself new. Maintained the original factory 24 parallel setup with the factory taps still in place on each terminal. I want to install a 12 volt winch and only desire 12 volts out of the 24 volt system. What is the easiest way to accomplish this and someone please show me a setup wiring diagram or picts if possible. Thanks for you help in advance.
