Nice Setup, I will be doing mine on Friday the True isolator with the two meters and an extreme pc925 battery, my question is, I have a 2017 and it has a ground brought up from the motor, that ground that I have connected to the negative side of the winch solenoid. Can I also use that same ground that goes back to the engine for my negative connection on my extreme battery. I wanted to get your thoughts. Thanks for your help
I don't see why not... I'm not sure what gauge the factory ground is but you could always jump over to the stock battery or add another ground to the frame under the hood. I would run the winch ground to the second battery and then run your ground from the battery to the winch solenoid. I'm certainly no expert... but I asked a lot of questions, read a lot of posts and my s*** works! So take it for what it's worth! Lol..
Thanks for all of the help JTW. Ive got my isolator ordered, now need the fuse relay box. I was toying with the idea of a fuse box for each battery. One for accessories that will be used with the key off and one for accessories that will mainly used with the engine running. Thoughts?
If your not running anything off the ignition that is high amperage you can Use one fuse box. You can run the ignition signal from the black and white wires under the Oem fuse block to a relay and run your load wires off the add on fuse block. Both circuits will be fused that way.
There is no need.. one fuse box with all accessories ran off the second battery and the true battery isolator Is all you need. That eliminates any starting issues from accessories but you can still run accessories with power off.
Yes.. mine is on a switch. I considered accessory power but then the key has to be on if you're just listening to music or need some light. This works well for me.
Yes.. exactly. My master switch is lit off accessory power and the rest are off the 2nd battery. The only thing the stock battery feeds is it and the stock battery voltmeter. This isolates the stock system as much as possible.
