Thread: battery drain

some cars the power port stays on key off, some turn off when the key is off, has nothing to do where its made or sold.

get the battery load tested too. as well as the alts volts.

you battery is likely dead, i also lost the battery in my tahoe 2 weeks ago. failed to even take a charge, or jump start. best i got was a slow crank and click click click.....

always unplug your power ports when its this cold. the extra drain will help kill it over night.

that fan turning on is also a issue, ignition harness gone bad could cause this, or maybe the fan resistor is going bad, some how its getting power with out being told so. you could pull its fuse and see if the batterys dead in the morning to.

okay I jump started it around 4:30 am no problem think it was still -5 out also battery is a duralast gold and I had them test it a month ago or 2 now that I remember and they said it was good
also I have the voltage meter on the DIC it reads over 15 volts most of the time sometimes surges at idle but its intermittent idk if this means anything.
also I got the new ignition recall from GM like a year ago (I know late to the party) do they change the ignition harness when they do that?
fan resistor is fairly new as well probably just hitting 2 years and I just did the cooling fan motor less than a month ago both failed in the dead of winter while i had an hour commute.

always had problems connecting any obd reader to the system scangauge connects fine for some odd reason but even the $700 obd readers at parts stores have a really tough time reading most times just dont work also have 2 Bluetooth ones that i don't think ever worked but work fine on a friends 2005 gp could this be another indicator of a bad ignition harness
