C-6 @ battery cut off devise

[Ed H.]

I am asking for some technical computer stuff info. I am preparing my 2007 LT3, Z51 @ J55 base engine machine. The RPO's included Heads up display, Nav, XM radio, voice operations of the audio and Nav systems. My question is, what are the chances of the loss of some of these functions when, by NCRS and some fire standards a battery cut off switch is used for judging. The most critical loss would be that of the Nav system.

ED, my 2008 Z06 only needs the windows recalibrated when the battery is disconnected. Windows all the way down and then all the way up and hold the switch for a couple of seconds (I think the owner's manual says 3 seconds, but don't hold me to that.) It has been a long time since I read the manual. Easy Peasy.

Ed,

As I recall, if you disconnect the battery and then re-connect the battery, you may notice the clock not working. If you find this is the case, there is an update that will need to be downloaded into the car computer to get it back. The download is done through via CD. Once you update the computer, the clock will show following any situation where the power is disconnected and then reconnected. Just an FYI.

The clock issue cured itself on my 2008 a year or two ago. Works fine now. Anyone want a stack of blank CDs?

Ed,

There are battery disconnects by a fused by pass circuit to keep the electronics working, but can't start the car.

Re: C-6 @ battery cut off devise

Thanks to all, I will find that type of disconnect you mentioned Gary, how many seconds to I have between the disconnect and the connect moment, I remember my engineering class in the USAF, the product moves at 186,000 MPS, at my age I don't believe my arms can move that fast. I'll call my 15-year-old grandson to preform that part of the magic. Up and onward.

Re: C-6 @ battery cut off devise

I dont have a C6 to test but I wonder if power input thru the cigarette lighter would keep all the computer memory settings when the battery disconnect was being used.

Ed: If you still have OnStar you can get any update through them. I recently had my 2009 LT3 updated through OnStar.

Re: C-6 @ battery cut off devise

Figured I'd reopen this as many of us will start the C6 Judging after French Lick. I looked at JEGS part 10321. A disconnect with the infamous green knob and a 15amp bypass to keep the computer hot. I hate that knob as I've had three fail in the past.

Has anyone seen a similar setup with a guillotine blade?

Thanks all
