My 2004 Envoy's Volt Gauge will show a discharge upon a cold
start.By cold I mean like overnite ,below freezing temperture,about
20 or so. It will show discharge for about 7,8 Seconds then go slowly
to charge state.If you let it run for a few minutes,and restart it will not
happen.
Dealer replaced Alternator,but it still does this.
They claim they checked others and they do the same thing.
I find this to be a problem but they think not,Any ideas out there? :idea:

Hmm, I'll take a look tomorrow morning when I start up. We're out of really cold weather in Texas right now though.

Does it ever not want to start or does it seem to drain the battery?

:lol: Hi Steve, My Envoy starts just find I just think it is odd to have a
discharge condition at cold start up, only for a number of seconds,
then everything is normal. Matt :roll:

I'm not sure what to think of that. My TB does not show a discharge at all when starting cold. It's not all that cold down here though compared to in Wisconsin! That's crazy cold.

.... although! They did replace the alternator, so there must be something funny going on. I would just watch it, maybe it's grounding out somewhere? Maybe a bat battery?

I heard there was a bad batch of batteries don't know if it was 05-06, 04 could be affected. I have an 06 and I live up north in the cold winter with no problems.
