Hubby went on business trip and left the cell phone charger plugged in on his truck.
Leaving for work this cold morning, I noticed the rear tail light and dashboard lights were blinking. Once I unplugged cell phone charger, it stopped.
My car has two cig lighters, one works even with the car off and one only if it's on. I plugged a charger in that charges my camera battery while at a softball tournament. We were there for about 5 hours. My daughter went to the car a couple hours in and said she couldn't get the door to lock using the remote. She had to manually lock it. I went to the car later, same thing. Hmmm. When we went to leave, battery was dead. That's the only thing I had plugged in. Never had a problem since then. Who knew?
The camera drew A LOT of amperage, apparently.
Key-Off Battery Drain
Never mind.That takes an extended period of sitting dormant; like keeping a car in storage without a "battery tender." I know you know that; but draining a battery charging a camera? That could happen if the ignition switch was in the "ON" position for the length of time mentioned and other things like fan motors or some other accessory was also on. Even prolonged use of accessories with the key in the accessory position will drain a battery; it just takes a tad longer because there aren't multiple 12v draws on the battery; usually just a radio/CD/tape player; no power to electric windows or fan motors. Just puttin' it out there.![]()
Never mind.
It is still KOBD
Not to change the subject but.
I have an older vehicle to when sits over a few days the battery is dead.
Took the battery in for load test and they said it was good.
Alternator voltage checks good.
Now I am try to diagnose for key off battery drain.
I found this: http://www.aa1car.com/library/battery_runs_down.htm
Will try it this weekend, but any other good checks?
Edit:
And prior to this happening I smelled something burning and noticed the radio doesn't work.
But I was thinking when something burns up it would create an open. I can check that by pulling the fuse.
Yes, I found the problem, I hope.
Hooked up the meter and the battery was drawing 176mA.
Pulled the breaker for the radio and it dropped to 15mA.
How old is the battery? It may just be showing signs of age, and this cold snap exacerbates it.
Actually this happened this past summer. Nothing with the battery since.
Did the blinking stop after you plugged the charger back in, after letting the truck run a bit to recharge the battery? How long had the truck been sitting with the charger plugged in?
Even a cell phone that is plugged into a 12v cig lighter can drain a battery if left for an extended period; even faster if it's cold like it has been. This must be an older truck. Many of the newer car's/trucks' cig lighters/accessory jacks now power off with the ignition switch to prevent this.
I was kind of directing that to both you and ShyGirl.

Agree, temps this cold are hard on batteries. I had a "no start" when we had the first hard freeze a month or so ago, car had started fine with no signs of electrical problems.... Then at 25 degrees, the ol' wah-wah-wah click click click. 10 minutes on the charger and started right up, but I took the battery charger and a 100ft cord to work. Sure enough, another no start at work.
Replaced the battery the next day. No problems since.
