Secondary Batery
Hello All,
So Im planning to install a secondary batery for the electronics in my travel Van (screen, playstation, Blueray, etc) and I found information for the oem batery tray, but not for the rest of the OEM diesel installation (wiring, isolator, fuses) How is the diesel secondary batery connected? |

direct parallel connection, no isolator, no fuses |
So simple and functional that its boring.. LOL

Okay, try this one on for size. On some gas models, a second battery is energized in to the system by a relay that senses a charge from the alternator. This is done so a depleted aux battery won't drag down starting the engine. I don't know which years have that wire, but I hope mine has it when I can add an aux battery.

That wire is supposed to be in the harness somewhere. I would guess it is under the drivers seat, because it makes sense when the aux battery is on the frame under the floor, just behind the driver. And there's a tap for power large enough to handle charging there as well.

There are cheap RV charger relays that will isolate just fine. You might find one with a fuse built in.

Amazon has some nice prebuilt kits. |
Always run my trucks positive to positive , neg to good grounds. Never any problems and blessing of techs. Isolater relay is good though, think one that is timed though before closing contact with second battery.
