I'm with ya on this one. I have dual batteries with a reman 160 amp alt, and the big 3 upgrade. Since it's been 97 degrees, If I have both cooled front seats on, the a/c on full blast, and K5L efans running on hi 90% of the time, I see 12V at red lights. It purks up when moving. I know there has to be a way to keep constant amps.
ya that's the problem i'm having when the cooling fans are on high there sucking the juice down hard, I was testing the system with basically everything on lights, flashers, both seat coolers, a/c front & rear, wipers on high, rear defrost. lol, the wipers actually just stopped working never had that happen before motor must have overheated, once i restarted they worked again.

I disconnected the rvc sensor for now and with just the headlights and a/c going and cooling fans on low it was giving me 13.8-14

I might contact the company that programs the bcm's for led's and see if they can do something with the rvc also I thinks it's called "white's services" or something like that I'm sure it's just a google away, but probably have to wait till monday to find out anything

Nothing at the moment because I am not home but I did get FedEx confirmation that the ARH headers are on their way. I have a short list of things to get done on the Escalade when I get home.

while I was swapping the battery's it decided it didn't like that very much and threw a "service security system" at me, busted out the tech2 and sure enough it showed a code, but it wasn't giving me a security light, after about 15 minutes of screwing around with that I disconnected the battery again for a couple minutes, hooked it back up and it started like nothing happened.

Ok. Got me. What are we looking at??

@Doubeleive posted a bulletin (that may have been from GM) outlining this. If I'm ever somewhere and the latch fails or I have no power and need to pop the rear hatch, I don't wanna have to need to drill a big hole first. This 30-second mod may save me a big headache one day.
