voltage drop, Gryphon resetting?

It does seem like this factory battery is a pathetic POS though.........I think it only has 500cca.

Chris, you might want to look at this thread: http://dygytalworld.ehost-services13...read.php?t=259 In post #4 I talk about what I discovered regarding current draw on the battery by my 2005 truck. If the battery is weak or it's very cold, I think the symptoms would be exaggerated.

One thing that people forget is that as voltage drops, current draw goes up. This means that as the battery falls below 12v, the current draw form peripheral devices goes up and causes the battery to discharge even faster. I don't have any data on the slew rate of the discharge vs. time, but suffice to say that it becomes quite aggressive as the voltage falls.

thanks for the info Jack and Bill............I am obviously a victim of this. My truck sat for a week (I was down south) at -30 degrees celsius.........when I got back and tried to start truck......click, click, click - no juice!
I guess I gotta unplug programmer next time or buy a much bigger battery!

You might also think about a battery tender for your truck if it is parked where you could keep it plugged in. I have one now and have not had any trouble since using it.
