Open door = dead battery!?!?

Recommended Posts

I went to a motocross race yesterday and at the end of the day my FTC (Cargo) battery was dead.  The doors were open quite a bit throughout the day. Im surprised that this killed the battery as I have left the doors open for a day while in the race pits and have never had this problem before.

 

I'm wondering (a) does it make sense to others that having the doors open all day would kill the battery?  (b) is there something else I may have done yesterday that may have killed the battery or (c) is there a way to disable the dome lights if this is what killed my battery?

My interior lights go off after a period of time when the doors are left open.  You didn't say how old your TC is or if it's the original battery or not.  An aging battery will eventually give up the ghost doing ordinary things it can handle when it was newer and in good shape.  If your battery is more than 4 years old, at least it gave you a warning that it's time to replace it, rather than just not starting one morning when there's someplace you really needed to go  😏

Sorry for the lack of info. It's a 2018 Cargo LWB. I bought it in November, so the van (and battery are less than a year old.)

 

Is there a way to modulate (or turn off) the brightness of the dome lights in the back of the van? There's a switch on the light in front, but I can't find a way to turn down/off the rear lights when a door is open.  Likewise, I'm looking for a way to turn off the outer parking lights when a door is open.  Anyone have any ideas on how to do that?

My battery has gone flat several times. Today the latest. Could not get the car running after it has sat outside for an hour after a two hour drive. I had forgotten my laptop charger in the 12V socket but it should not kill the battery in an hour. There’s definitely something wrong with it. Had a towing service give me a jump start. Should really get a battery pack of my own.

 

Drove back home for two hours and the battery charge had only gotten up from 48% to 65%. Charging voltage seems fine (14.3V), battery voltage during charging is 14.1V but after that it’s 12.3V (at 65% charge), which is basically a dead battery.

Check out this thread below for a thorough discussion. Since you have a 2018, the dealer "should" be able to disable the approach lights. Or you can do it yourself using Forscan with the right ODBI reader. In the meantime, if your driver's window is down, you can use the high beam lever to turn off. Push forward then back. Better to have that featured disabled permanently. Good luck!

 

PS - If you don't have one, as poster MRTN mentioned, good to have a jump start battery pack handy. I now have one for both our vehicles. There's a thread about this subject as well.
