rvc charging with dual battery's-looking for information

[Doubeleive]

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

This is on a 2010 SSV. It goes straight from the negative terminal to the block.

I've wondered that too, when I added my 2nd battery, I didn't add another RVC sensor. I just ran a ground to the frame, and the positive to the positive on the other battery.

ok, so does it still retain the RVC sensor on the other battery or is it eliminated all together like on the 2500's

I use 2 AGM's with both side post's and top post's, I bought a ground cable for the nbs which use's the side post so I can add a extra ground to the passenger side battery, and then I am thinking of adding a positive wire to the alternator for the drivers side battery using the same side post method from the nbs, supposedly the grounds all need to run thru the RVC sensor for it to work properly but if they didn't run it that way on the ppv/ssv then I will just not bother to even use it all

When i did my set up i looked at many pics of ppv/ssv’s for sale online especially ones with the hood up and and downloaded the Upfitter stuff and and never saw an extra rvc sensor. It appears to working correctly so.. meh whatever

Neg run from passenger batt to alt bracket
Positive run from passenger side to starter

ya that is how I have mine now basically, I am just adding a couple extra side post cables one was $17 and the other is $9.00 I figure it couldn't hurt, I started wondering after I had a stored code for the RCV reading incorrectly or something like that but it could have been there since I had unplugged it once to see what the volt meter showed with it disabled. On the other hand it seems like my voltmeter has been just sitting on 14v+ lately and not moving around like it used to

Just pulled the extra cables off of my 2013 PPV yesterday. Driver side battery negative cable direct to cylinder head, positive cable directly to starter terminal just as Galante has shown above.

does the passenger side battery still have the RVC sensor

Just had a look, it does have the sensor on the passenger side negative cable.

great thanks.

Doubie, what you find out? How is the harness run? Part numbers? Now im curious....even tho mine has been fine for the last 3 years, even with running the plow. My gauge shows what it’s supposed to and even sits at 14.3 +/- when i have tow/haul on like its supposed to do. Dvom shows same-ish and both batteries are always charged.

these guys say the rvc goes like normal on the passenger and straight to ground on the other side, I only started to question it because my voltmeter has been 14+ and I was watching a video on the mechman alternator and there instructions say to run the ground thru the sensor if using 2 battery's, but apparently this is not necessary and I had a saved bcm code for some kind of voltage error I think my sensor took a dump and I don't think there is a way to test it without going thru a bunch of rigamoro with a electrical meter, so I just bought a new ground cable and sensor since it was only like $45 I figured I would install that and disconnect the batterys for a few minutes and see if it reset's starts going back to normal, but it's been raining for the last 3 days so I haven't had a chance to get installed yet.

Are any of you guys running stock alternators with the dual batteries, because im doing a dual battery but wondering since in my 16’ tahoe i have the 170 amp alternator !
