Truck won't auto-stop anymore

[jzweedyk]

I’ve run a battery charger with 3 drone batteries charging from my inverter, I don’t remember stop/start disabling. I read that from the manual too. Maybe there has a to be a pretty significant load on the inverter?

I run an Ipad off the inverter. If the Ipad is fully charged when I start, the stop/starts works. If it is not, so the load is running the Ipad and charging it as well, the stop/start does not work. So there is a threshold where it turns off the start/stop. along with a bunch of other things that turn it off.

so is the battery just WIMPY or is auto start stop as well as other uses ( like using the 40+ thousand lumens of B/D lights along with a high bass output stereo a lot ) etc., etc. just frying the daggone thing faster. One thing I notice is that long lights the stop start will give up even in average temps - we’ve got some long lights around us, I think the longest is 7 minutes, the truck keeps everything running just like the engine is on, lights, stereo, heat, heated/cooled seats, etc.

did you notice any slow starting?

No I didn't notice any slow starting. I did see something the other day when I turned the truck off, something on the nav/radio screen about low battery. I saw it but didn't really think about it.....

Didn’t we have a guy who had a mystery drain and IIRC it turned out that Sync was turning on moments after you depart / lock the truck and it stayed on, sucking the guy’s battery dry.

I’ve done the exact same Thing. Charging drone batteries and my start stop was indeed disabled. Based on my observations even the tiniest of load on the inverter disabled start stop

Curious why you’re charging off the inverter with multiple USB outlets available in the car. I haven’t done a current draw test but based on the charging rate I’ve seen, they appear to deliver the full 10-12watts the wall charger provides.

I am using two of the USB outlets (I know there are more) and the inverter plug is right next to the Ipad. It is just convenient.

I like the auto stop AND the exhaust sound! Lol

Battery is now at 60% according to the battery tender I just reconnected. Down 40% in a week. Drove the truck 120 miles last Saturday and then it sat until I drove it 25 miles Thursday and 25 this morning. I’ll take it in next week for them to check it out.

My money is on sync and its hardware. I’m betting it’s turning on after you leave the truck.
