Hey all....
I'm wanting to do a custom Dual Battery setup on my 84 CJ w/258.
Before you jump in and tell me how to wire it up, I need to tell you that this won't be the normal Dual battery setup.
what I want is this:
Battery #1: hooked up normal, running the vehicle.
Battery #2: Will be ONLY running the radio........ Thats' right.... ONLY RADIO.
But I want the alternator to still have the duty of charging/maintaining #2 battery also. I will be wiring the radio directly to the #2 battery, no ignition required.
The motive: I want to be able to drive to the beach, the woods, a parking lot etc... and run the radio until it dies.....
Then hop in, and crank it up and drive home, without having to flip any switches.
That's right everyone, I'm so stubborn and spoiled that I want it done my way
I'm thinking I'm going to have to have some kind of diode hooked up so the voltage from the #2 battery, won't "backfeed" the system through the alternator connection, but this is why I'm reaching out.
I would ask my Electrical Engineer/Physicist father, but he had a hard time mounting a flat screen on the wall. So...
Any input is greatly appreciated.
Please keep in mind the terms of the "motivation" though...... Radio will be left on at anytime, running the #2 battery down. #1 battery can run the vehicle like normal.... NO need to PHYSICALLY flip a battery switch.
