What did you do to your NNBS GMT900 Tahoe/Yukon Today?

I think more people have dementia than we realize. Laugh off everything, never at fault, only think of themselves constantly..
Hopefully they'll be gone sooner than later.. And hopefully I won't get it.. lose a few brain cells here and there, who knows what's left..

all the chemicals in the environment, the food, the drinking water certainly does not help.
the only saving grace is our bodies shed most of it naturally. I think some gets stuck in the brain matter though lol

the amount of free case you have basically decide how much you care about taking responsibility for things these days.

But when that happens you won't know it, or care.

Your battery is in the normal spot, other spot behind headlight is the aux position.

ya that's all normal on the gmt900's they swapped things around, maybe the silverado was already modified when you bought it? figured you would already be familiar
looks like you need a fuse box cover or did you pop it off?
what's the history of this thing? looks like it spent some time in the rust belt that power steering pump and line is looking nasty and some frame rust?
check your brake lines

I did not realize GM did that. It looks weird but makes sense as there’s more room to work on that side of the engine. As for the Silverado and its battery…the body shop couldn’t find it and had to resort to following the cable from the starter to where it is, behind the front bumper. The engine bay in that truck is completely modified in order to make room for the wheels to completely tuck into the tubs when it’s aired out and laying on its rockers. The fuse box is relocated to where the battery was among other things. I told him he could have called but I guess he wanted to play the game of “ where’s the battery?”. It’s a fun truck to work on for me at least. I know every square inch and where every module is since I’ve had them all out at one time or another when I converted the interior from an LS to an LT.

the open spot makes it easy to add a 2nd battery or whatever.....
I made mine into a parallel 2 battery, all it takes is a battery holder (the same one used since forever), the cable from the battery to the starter (it clips right into the existing harness under the engine) and a ground wire.

After 700+ miles, the readiness monitor tests finally all passed. I blame the cold weather for jacking up the test parameters for so long.

That is a mod I would like to do, especially being as I live where it gets to below zero at times.
Is there a write up with part numbers and whatnot?

the easy to use oem power cable is getting kind of scarce but there are a couple around p/n: 25825642
it is a plug-n-play cable from 2nd battery tray then feeds under the engine to the starter, it clips right on the existing wire harness.
then you need a standard battery hold down

and then for ground I ran a 4gauge from the 2nd battery along the firewall over to the 1st battery ground post, that one I had made by a battery shop because nobody sells that one. i just took a tape measure and measured from the 2nd battery ground post to firewall and then across over to the 1st battery added a couple extra inches to that and had it all crimped like oem and then put loom over it to make it look stock. I did it that way because around that time I was having issue's with the RVC so doing that made sure the RVC could read the ground load properly. some people feed it thru the sensor but there really isn't room in that sensor to do that and you have to take it apart to even try.
at first I just grounded it to the alternator bracket but later decided it was best to join both grounds together as it should be done anyway as a best practice.

rvc charging with dual battery's-looking for information

curious on how the rvc system is setup with the ppv's with dual battery's does the ground from the 2nd battery run over to the passenger side and thru the sensor?? if so any pictures? or a ground wire part number? thanks for any information

There are two different options. One option doesn't use an isolator and one does.

I prefer the isolated option because if one battery dies you can jump start yourself off the other. When connected in parallel without an isolator both batteries discharge at the same time.

I believe there are some write ups in the PPV section.

 

[Doubeleive]

I chose to do it parallel, simply because the chances of getting 2 dead batteries at the exact same time is pretty much nill, yes you could probably drain both "somehow" but what are the chances? i also did it because I run a good sized audio amp and subs so the extra juice is a win/win
adding a isolator though is also pretty easy to do, there are crap tons of them in the boating marine market on amazon, some with remote fobs and the whole shebang
