Has anyone successfully rerouted the feed to the 400W inverter from a second battery vs from the stock feed?
Ya I found that. It's right behind the stock battery. ( I O gree about the red)Pages 214 & 215 clearly show B+ from the inverter connecting through a relay and then through an 80Amp fuse to the battery...It is a Black cable, which in my opinion is a poor color choice by Toyota, as black should be reserved for Batt-
Good points. I think I'll take your advice. I wonder what gauge is used for the stock 400W. I have #6 running into the cab now. You think that's too small huh? Also, what amp fuse will you use for that 1000W?Once I install the second battery on the passenger side fire wall I will install the 1000W inverter I have up under the glove box on the passenger side. Two short #2 wires will supply the inverter. 120V wires can be run anywhere on the rig from there.
You are better off keeping the inverter as close to the battery as possible as you require a high amount of power to run it. Once the power has been converted to 120V the gauge of wires required is far smaller, 12 or 10 gauge will work well, just like in your home.
