Battery Relocate Tips

[Ne-max]

Putting my batteries in the back of my truck. How does everyone run the wires? Also have to do a cut off switch. Was thinking of running one big wire down passenger side right to starter. Then another one down the drivers side to a junction box for factory fuse box, electric fans, lift pump, and trans cooler fan. This is all new to me. Does the cut off switch just need to kill engine or all power to front of truck?

Normally a kill switch will kill all power.

Normally a kill switch will kill all power.

Alternator is also suppose to be shut off is what I was told.

It needs to remove power from alternator and battery I believe.

So a double pole single throw switch (DPST)?

I run welding cable from my switch in my bumper to the starter to make sure I didn't have much amp loss. Yes needs to kill both battery power and alternator, or else it will back feed and stay running off of it.

Do you just use a 4 post and run your alternator charger wire to it? Basically run 2 cables for it and starter?

You can either run a double pole switch, or run your alternator output wire back to the battery side of the switch. Then when you hit the switch, the battery stays charging for a second (engine is still rotating), but the ECU and everything else turns off so it dies.
